A bit short on details but the GoogleTV Facebook page is hinting at some “big announcements” for GoogleTV coming Monday.

Whole Home Music Streaming Device?

Some are speculating that it will be a Sonos competitor based on a WSJ article

“Google Inc. is developing a home-entertainment system that streams music wirelessly throughout the home and would be marketed under the company's own brand, according to people briefed on the company's plans.”

I suppose that is possible given Google’s continued attempt to bring Google Music to peoples attention, but I suspect the announcement will be one of two things:

Guess #1:

New content providers – the new Verizon/Redbox streaming solution discussed this past month could be one of the new providers and there is certainly room for others. This would be a “nice-to-have” announcement, but wouldn’t be “big” in my eyes.

Guess #2:

New GoogleTV Devices – this is more of a long-shot, but this is the one I hope we will hear about. I know that Google has a team working on some significant upgrades to GoogleTV that could bring it closer to the Media/HTPC world (more on this soon), but I didn’t expect anything until later in 2012. It’s possible they want to give the world a sneak peak at what they are working on to beat Apple to the punch.

Guess #3:

Some sort of software update? Google has said there will be several updates coming this year – in particular Ice Cream Sandwich (Android) will come to GoogleTV. This could be that announcement.

On a sidenote, I find it curious that this tease from GoogleTV was posted only on Facebook and not on Google+. The Google+ GoogleTV page has nothing about it at least thus far.
