An email received by a customer regarding the availability of an update to fix long-standing reboot issues has confirmed that HTC plans to roll out an update to fix the issue as well as update the device to Android Gingerbread:
I understand how important it is for your Thunderbolt to function properly and I apologize that you have been experiencing rebooting of the device. HTC and Verizon are aware of this issue and an update will be released soon that will address the reboot issue, and bring the Gingerbread 2.3 upgrade on board, as well as several other enhancements.

The update to Android Gingerbread was previously confirmed earlier in the month via screencaps of Verizon internal documentation, although the update was initially meant to be shipped as a basic maintenance release with the reboot fix which was subsequently leaked and made available.
