One of the affected models, the Thunderbolt, only now started getting updates to Gingerbread this week. That is, until Verizon halted it due to a major usability bug that should have been identified easily in carrier testing (voicemail notifications don't work).
Given that it took it took HTC this long to get an update to an Android version that's been available in source since December and they still managed to mess it up, I don't have high hopes for something like this getting fixed.
There are only two ways I recommend Android - use a Google-branded phone that Google will provide complete OS support for, or go it alone with OS updates from a 3rd party.
For non-geeks the first option is the only viable one, IMHO.
