Ok good call, I had not thought of that.
Still seems like them taking a masive gamble though. I mean when the new OS comes out, most firms and people would have upgraded anyway (maybe not quite as quickly but they still would upgrade at some point), tying it to a specific hardware upgrade means a lot of people and firms will hold off until the last moment and will strongly consider other options in order to maintain current hardware. Seems a good way to drive your customers away long term for a very short term gain...
