When When will Windows Phone 8 be released? was asked, it made me wonder if speculative questions should be off topic.
On the Android StackExchange, they specifically made questions like When will X be available in my country, and When will application Y be released off topic. Should we do the same? This is the thread I can find that explains why.
I feel like for the majority of them we can only speculate. For the few that we could give a solid answer on, It would be a one-liner:
It was announced at X that availability would start on Y
Should we just make these off topic as well?
