HTC just posted on its Facebook page some details regarding the upcoming Android 4.0 update for many devices:
HTC has been working hard to get its Ice Cream Sandwich upgrades ready, and we’re excited to announce that our first round of ICS upgrades will roll out by the end of March for the HTC Sensation, HTC Sensation 4G and HTC Sensation XE, followed soon there after by the HTC Sensation XL.
In addition, we can confirm Ice Cream Sandwich upgrades will be coming later this year to the HTC Rezound, HTC Vivid, HTC Amaze 4G, HTC EVO 3D, HTC EVO Design 4G, HTC Incredible S, HTC Desire S and HTC Desire HD. Stay tuned for more updates on Ice Cream Sandwich releases in the coming weeks.
It's probably safe to assume that that the US version of many of those devices, like the Droid Incredible 2 or the Inspire 4G, will also be receiving the ICS update, though we can't say for sure until an official announcement is made. Either way, this is definitely good news for many HTC owners.
