I see what you are saying and all but unless sony and microsoft really tried then they will make a pretty decent jump over the WiiU. It wont be as big as the wii vs ps360 but it will still be different. Let me put it this way. let's say hypothetically the Wii is a 2 in power. Well then the 360 would be a 5 and the ps3 a 5.5. Does that sound about correct? Ok now let's move on to the WiiU. Likely itll be pushing a 7 by the end of its life so that is 1.5 more powerful. Well if that is true then ps4 would likely an 8-9 as well as the 720. Why because both of them with current technology will probably be at least a 1.5x increase.
Scrap all that for a second though. The one thing you did get spot on was the Sony and Kinect issues. Sony PS1 and PS2 were pretty weak in power but were very successful. PS3 had a different strategy and was pretty much a failure until it's later years. Now they are financially unstable and have dropped down to AA status along with the strong yen. Likely this will cause them to cut on hardware. Kinect 2.0 will be bundled most likely and yes that will keep it's hardware from going up too much as well which is why I think we won't see as big of a leap as we did this gen.
