Pretty awesome that Samsung intends to update not only the S3, but the S2 to JB. They seem to do a good job eventually putting out updates, even if it takes forever.
I'm honestly surprised Motorola is updating the RAZR series to JB- they're notorious for abandoning phones.
Sony also does a good job with their upgrades- if some of the 2011 line gets JB, that would be awesome. I'm a bit sad they had to abandon the Xperia Play on Gingerbread, but I can understand that, I guess. They prioritized the gaming experience first, which on both their beta ICS ROM and the aftermarket ROMs like CM9, it's clear gaming performance and compatibility took a hit. Not to mention the thing has something like 512MB of internal memory for both the OS and applications.
HTC... HTC is slipping. The Rezound JUST got ICS yesterday. I think they owe it to their Rezound adopters to push out a JB upgrade, but they're withdrawing from markets, and their revenue predictions for the future have looked grim.
