There is no way to rule out GB as the cause of this failure right now. All we have is theories and the best fitting one is an emmc chip failure. Until we can find a user with a brick, who is still s-off, we can not learn more.
DO NOT FLASH OVER BRICKS, We need you to have s-off for trouble shooting.
UPDATE
We need info from brickers and non brickers please see

It has came to our attention, over the last few days that the recently leaked Gingerbread radios maybe causing a oddly large number of bricked phones.
This can affect any Thunderbolts running Gingerbread (except CM7 users), even after running fine for several days.
The cause at this point is not completely understood, and AndIRC as a whole recommends you revert back to Froyo until we understand it, or have a new leak.
When bricked, the phone is sent into an endless bootloop, no matter if you are booting into Android itself, or into the recovery. Trying to revert after the bootloop does not fix this issue.
Theories:
GB Radio causing corruption on the emmc:
Undisclosed chipset issue (Sorry no details will be coming unless verified)
GB miss reporting battery stats, aka just dead battery (Debunked by ryan2600 and I)
"Not sure if its the radio, i got a bootloop experience this morning after tethering my tablet on a freshly charged tbolt, few minutes later the phone died and stuck in a bootloop, there are times i can go to bootanimation sometimes it goes up to HTC screen and dies, I can go to HBOOT but before i can do anything the phone dies.
Good thing i have a 2 extra battery and an external charger from ebay, I swapped the battery and my phone is back to life, it seems like the GB roms are not charging the battery properly and reporting that the battery is around 80-90%" http://www.reddit.com/r/Android/comments/hk54l/if_youre_using_the_leaked_gingerbread_build_or/
