There is a lot of speculation without getting the complete facts. HTC has now provided an explanation as to why the Desire HD updated could not be made (HTC explains decision to drop Desire HD Ice Cream Sandwich update | Android Central
). As you can see, the problem has to do with the partition in the storage which is too small for ICS. The Desire HD only has 1.5 GB of storage, while the TBolt has 4 GB of storage. Hopefully the partition space is large enough for ICS on the TBolt. At least, there is more room for it than on the Desire HD. The issue is neither RAM nor CPU-related based on this explanation, so until they say the contrary, I will continue to wait for this update.
