Those are devices that will probably get the update because they basically just came out. I don't think we will see an official update from htc because...
1) it costs them money to update an aging phone
2) its gonna take a while for them to integrate sense into ics, I don't see it happening till next summer, by then the thunderbolt will be considered eol
HOWEVER... the thunderbolt is perfectly capable of running ics hardware-wise. I don't know about you but my single core handles anything that I throw at it with ease. We have some awesome devs that will continue to produce roms for the thunderbolt. The fact that the galaxy nexus is a 4g device will make it easier to make ics roms for the thunderbolt which was admittedly tough to make roms for at first as it was the first 4g lte device. So my advice is root and be happy

we'll see some ics soon enough
