We are still a week away from the release of the Droid DNA on Verizon and the device has already been rooted! Not only has it been rooted but it has also already received custom recovery! This paves the way for Rom development on this beast of a phone. The method relys on the fact that the bootloader is still unlockable via HTCDev which could possibly be changed once the phone is released.
To Root you will need to first unlock via the HTCDev bootloader unlock utility, then you will flash the unsecure kernel in fastboot, flash clockwork mod recovery, then boot into recovery and flash the root.zip file.
The whole process is actually not that difficult. You can find all the files you need and full instructions at the source link below!
