There are quite a lot of questions about the Windows 8 upgrade. You could reason that (some) of these questions are too localized as the offer expires at the 31st of Januari 2013.

I just asked the following question: In what timezone did the deadline for the cheap Windows 8 upgrade fall?

Which could be considered a good candidate for too localized. However I mentioned "You could reason that if for example there is a similar offer for Windows 9. That it might be relevant to know what the case was for Windows 8".

I'm not sure if that reason holds up, but I thought I'd put it up for discussion here on meta so that we can determine where the border lies.

(Maybe the title of this question should be made broader to cover all questions about such upgrades or new releases).
