The DROID Incredible has remained without Gingerbread while its successor, the Incredible 2, has had it for well over a month. A Verizon support rep is now claiming that the Incredible's long awaited Ginger-bump has been put on hold pending final approval from Verizon's product team - which basically translates to: we're not happy with it yet.
It could be a single bug, or wider user experience problems. This means the delay may last anywhere from a few days to a few weeks - or more. We'll keep you updated if more information develops, but for now, your guess on a date is as good as ours.
