The Gingerbread SDK is rumored to get released on November 11. Shortly thereafter I expect there will be a flood of questions "when will {phone X} get Android 2.3?" We're still getting questions like that for Froyo.
My idea is to have one Community Wiki question: "When will my phone get Android 2.3 (Gingerbread)?" that will contain as many models and dates as we can find. Many of us read a lot of Android blogs; whenever a new date is announced (even if it's a rumor) we can edit the question to have that information, with links to sources. (Alternatively, we could have answers for each phone model, but I think that would get unwieldy.) That way, we can then close every other question about an individual phone and point it to the CW question.
And, of course, being Community Wiki will allow more people to be able to edit it.
Thoughts?
Update: It would probably be worthwhile to have a Froyo question too. There are still devices out there waiting for that upgrade.
