Google’s hotly anticipated annual developer conference will kick off in just a couple days in San Francisco. And conference-goers and Android fans are excited about the possibility of new products the company may announce and/or give away.

But Android fans may be a bit disappointed if their expectation is brand new hardware. While the 2012 Google I/O conference saw the introduction of the new $199 Nexus 7 seven-inch tablet and the Nexus Q streaming media hub, the 2013 conference is likely to feature no brand new Android hardware. Instead, it’s likely that Google will refresh some existing products and possibly provide more details on some of its upcoming Android hardware.

That said, Google is expected to focus a great deal on software. And CNET has high hopes we could see a new version of the Google Android software. Whether it will be an updated version of Jelly Bean or the new Android 5.0 version Key Lime Pie is still unknown.

Here’s a look at what CNET expects to see when the sixth annual Google I/O kicks off on Wednesday.

Word found on the street is the fact that Google is planning to unveil an upgraded Nexus 7 pill. According to KGI Securities analyst Mingchi Kuo, whose report was picked up by the website website 9to5Google, the up-to-date Nexus 7 involves a quicker Qualcomm APQ 8064 processor, a 1,920×1,200 7-inch show with narrower bezel, a 5-megapixel camera, wireless charging, along with a body that’s 7.5mm to 8.5mm thick. The brand-new pill is moreover expected to be lighter than the past adaptation. Google is furthermore expected to keep the same $199 cost for the upgraded pill, according to Kuo. The modern pill can ship inside June or July.

Nexus 4 update

Google’s Nexus 4 is the 4th smartphone to receive the Nexus moniker plus to supply the pure Android experience for wireless customers plus programmers. The smartphone, that is surprisingly synonymous to LG’s Optimus G, was just introduced inside late October, whenever Google took the wraps off the newest adaptation of its Android software Jelly Bean Android four.2.

This fact makes it somewhat unlikely that Google would release a completely new device so soon.

But there have been rumors flying around over the past several weeks suggesting that Google will upgrade this device, giving it both more internal storage and faster 4G network access. Google makes the current version of the Nexus 4 with either 8GB or 16GB of internal memory. The phone is meant for a worldwide audience and supports GSM technology. But it does not support 4G LTE. This fact alone has made it a big disappointment to U.S. smartphone consumers.

The updated version is likely to have 32GB of internal storage plus 4G LTE support. The big question will be whether Google is able to maintain its inexpensive pricing for this device. Today the 8GB version of the phone sells for $299, while the 16GB version sells for $349 in the Google Play store.

It’s been almost a year because Google shut its $12.5 billion purchase of handset creator Motorola Mobility. Because then, eager fans have been expecting a fresh Google-built telephone which sports not just homegrown Google Android software however hardware also. There have been rumors of the new so-called Motorola X Phone for months.

It’s hard to know at this point if the supposed X Phone is an extension of Motorola’s previous smartphone products or if it’s been tailored made with Google influence.

While many fans would love to see the X Phone launched at Google I/O, it’s unlikely the product will be announced and given away to developers at the show. That said, there is a chance that Google will give developers more information about the new product. Some of the rumors floating around suggest the device will have a 4.8-inch touch screen and a Snapdragon 800 processor running at 2GHz. Some say the X Phone will be virtually indestructible sporting a hardened case and display that is even tougher than Gorilla Glass.

Google Glass details

Google Glass had its big coming out party at Google I/O last year. And when just a prototype at which time, the wearable Net-connected technologies got Google fans excited.

A year later, Google Glass recently began shipping to early developers and press. Google’s co-founder Sergey Brin has said that pricing and availability of Google Glass will be announced by the end of the year. Perhaps he’ll reveal more details at Google I/O.

Aside from shipping details and pricing, there is still so much to say about Google Glass that it’s very likely Google will use the conference to talk up how exactly people are expected to use Google Glass. As a result, there’s a good chance that Google may reveal some third-party apps that are being developed for Google Glass. Hopefully, we will get to see some cool demos during the big keynote.

Nexus Q upgrade

The Nexus Q was Google’s big flop of 2012. The streaming media hub was announced a year ago at Google I/O 2012. Priced at $299, the device, that didn’t do much alternative than stream Google Play music plus videos to alternative equipment, was watched because wildly overpriced provided its limited functionality.

Realizing the device wasn’t up to snuff, Google worked to make it up to consumers. Soon after the Q hit the market, Google delayed the product launch and offered a free Nexus Q to customers who pre-ordered the product. At the time, the company said it planned to redesign the Q. Nearly a year later, there has been little if any talk about the Nexus Q. But that doesn’t mean that Google hasn’t been quietly working to refine the product anyway. There’s a chance that a newly-revamped Nexus Q could be unveiled at Google I/O. Perhaps, it may even be bundled with Google TV, another Google product that has been slow to develop.

CNET will be out in full force covering Google I/O. The conference begins Wednesday. So stay tuned for more news.
