Looking at the sales, and in particular what seems to have sold well (in terms of particular bundles) I'd say the HD consoles are well placed to continue to grow in US (360 comfortably ahead of PS3 of course). Both will be taking share from Nintendo for the moment going forward, and if the Wii U doesn't recapture the market the US will be primarily in MS hands with Sony having a decent share.
Really curious to see how the Wii U performs when it launches and whether MS in particular, or Sony, launch close to it. If I was MS and Sony I wouldn't consider anything earlier than Q3 2013 at the moment - there seems no need. Both are still selling well HW/SW and neither has clearly peaked in the region or worldwide.
Try to be reasonable... its easier than you think...
