Microsoft is transitioning and Windows 7 is part of the old strategy, it's tied to different dynamics (that still work, mind you). Windows 8 and on, MSFT is trying a different thing with the devices and everything. I think it makes sense to keep these worlds/strategies separate. They're also making a ton of money on Win7 so why kill that stream of revenue? They can let it die slowly while they improve/tweak their Win8+ strategy.
