I got this in my inbox this moring:
HTC Desire HD owners who are hoping to get an official update to Android 4.0 Ice Cream Sandwich. Looks like we won't be getting an official ICS update.
Here’s HTC’s explanation for this:
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.
