I trust Anet ... I just like a good conspiracy theory. I doubt it was THAT much of a coincidence though -- I think once they had an idea of the release (a while ago as long as tests went well, which they must have), they purposefully announced it today, knowing we'd get a kick out of it. And maybe not.
edit: (but this was after people made much ado about nothing ... i.e. the jersey's didn't mean anything originally)
