Think Incredible 2 will get bump to 2.3.4 from 2.3.3 like the EVO 3D and Sensation 4G? Even the original DInc went straight to 2.3.4. I love my phone and have no complaints but feel a little left out...lol
I've learned to either:
A - Not worry about what version of Android is officially supported on a particular phone. The reality is that the changes from one version to the next at this point are so minimal as to be almost irrelevant. From 2.1 to 2.2, and then from 2.2 to any version of 2.3 was honestly anticlimactic, so going from 2.3.3 to 2.3.4 is even more so.
Or
B - Look to unofficial ROMs and/or market apps to support whatever feature I may feel is important. From Cyanogen to MIUI to any others, you can run whatever version of Android/Sense/Whatever you want, right now, today. And most major roms (CM7, MIUI, OMGB, etc.) are all based on 2.3.5, so even if HTC did put out an upgrade to 2.3.4, someone would immediately ask "where's 2.3.5 love2?".
Manufacturers will **always** be behind the curve to a greater or lesser extent. I agree with the other poster, that if this phone will only get 1 more upgrade, it would be far better that HTC puts it's time into ICS than a 0.0.1 upgrade to GB.
