Update 12/21: SE published a blog post this morning vaguely detailing a timeline as to when ICS should start hitting devices. It looks like the Xperia Arc S, Neo V, and Ray will be the first to get the update sometime in late March/early April. After that, the Arc, PLAY, Neo, Mini, Mini Pro, Pro, Active, and Sony Ericsson Live with Walkman will all receive the update as well, though no ETA for that bunch was given.

Sony Ericsson has been taking owners of Xperia devices on a roller coaster ride concerning future updates -- namely the update to Ice Cream Sandwich. They initially said that the entire 2011 Xperia line would be updated to ICS, only to retract that statement in the very same day.

Can you guess the next move? Yeah, ICS is back on for 2011 Xperia devices. We're pretty sure it will stick this time; after all, it doesn't get more legit than an official blog post, right?

Devices including in the mix are the Xperia Arc and Arc S, PLAY, Neo and Neo V, Mini and Mini pro, Active, Ray, and Sony Ericsson Live with Walkman, though no word on an estimated availability was given.

Now I just hope someone from Sony (Ericsson) reads this post so they can see how good their device names look with proper capitalization.
