Sony never really left, even their worst selling home console reached 80m and it still has better legs than the 360.
With the WiiU and XBone, there's really nothing Nintendo and MS can do. The WiiU is dead without solution, and the XBone is too similar to the PS4 minus power and japanese support to compete without big money losses. The NX will have to mix the handheld and home console audience to double Nintendo's software output, keep and reward those 3rd party companies that still work on handhelds and create an userbase big enough to attract the western publishers and other multiplat makers. Microsoft could expand the XBox services through consoles and PCs. They could create a Steam-like digital service and create the Steambox Valve never could.
