Having just procured my Incredible earlier this week, I'm still getting my bearings in 2.1 although the OS is so intuitive my learning curve is rapid.
Although it was only for a few months until X launched, the Incredible was VZWs flagship device. I think before long we'll either see the update OR an official communication from VZW.
Bear in mind in situations like this, if in February they say "It's coming in August" and then in April they restate their timeline, typically a restatement with that type of lead time is measured in months, since that typically means that very early on it was abundantly clear they will get no where near their target date.
However, if in February they say "It's coming in August" and then mid August they revised their timeline, typically a restatement with that short of lead time is measured in days or (at the worst) a week or two, since they must have been tracking along their critical path until the absolute very end where one or two small issue threw a wrench in things.
That's been my experience anyway. Since we haven't heard a clarifying statement from VZW I'm still optimistic that it will drop any day now.
