A bit of backtracking now, just got news that the Desire HD ICS update is INDEED cancelled. Reasons for that is still not made public, but I guess that they got pretty good reasons for it.
“After extensive testing, we’ve determined that the current version of HTC Sense with Android provides customers with the best experience on the HTC Desire HD. When we consider new versions of software, we weigh a number of factors, but ultimately the customer experience on the product is the deciding factor. We apologize for any confusion this change may have caused our customers.”
The ICS update for Desire S is still on. This is just VERY badly handled by HTC, and they know it as well. Might lead to changes in how the communicate about things.
