While Sony Ericsson clearly said that they will move on latest Android Ice Cream Sandwich OS sooner or later. But HTC is very quiet until now. Now they give us a quick update via their Facebook page in regards to Ice Cream Sandwich coming to their devices. Essentially, the update provided no update at all as the statement repeats sentiments often put forth by PR folks when questioned on whether or not certain devices will see certain software.
I am eagerly waiting to see Desire or Sensation handsets running latest Android OS with their own Sense UI.

“Since Google unveiled Ice Cream Sandwich earlier this week, HTC has been looking closely at the new OS’s features and functionality to determine our upgrade plans. We’re a recognized industry leader in providing fast and consistent upgrades to our Android devices (see what Engadget had to say about our upgrades: http://engt.co/qMb9nQ), and Ice Cream Sandwich will be no different.
Upgrades require a careful balance of hardware and software to ensure the best possible performance and usability, so please stay tuned as we assess our product portfolio. Our goal is to upgrade as many HTC devices as possible and we’ll be sharing details on specific devices and timing in the coming weeks!”
