Manufacturer HTC today on its Facebook page gave word that its initial round of Ice Cream Sandwich updates will be available by the end of March. First up are the HTC Sensation, Sensation 4G and Sensation XE, with the Sensation XL to follow. (Note to HTC: Got enough versions there?)

That's just for starters, of course. Back in November, HTC told us that the Rezound, EVO 3D and EVO Design 4G also would receive updates as well. And today, HTC has added the Vivid, Incredible S, Desire S and Desire HD to the update list. There's no word on when they'll be updated (other than "later this year"), but it's certainly a good start.

Here's HTC's full statement:

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.

Not a bad roster, indeed. But notabily absent remains the likes of the HTC ThunderBolt, one of the more popular Verizon smartphones of early 2011. Anyone feeling left out?
