Yep, I'm on board with Jaffe's crystal ball gazing. I expect I probably won't be gaming much by the time PS4 / 720 get late into their cycle so it won't really matter either way.
I expect you'll get something like an internet hub device that's used for all devices and functions around the home, and gaming will be one of those functions. It'll basically be like Cable TV is now I expect, and there will be multiple manufacturers, not just "the big 3". I don't see Nintendo home consoles surviving the transition.
I even wonder if mobile devices that are game consoles first and does few other things. Xperia Play might not be a good hybrid device, but I think it's the way things will go. Nintendo will have to adapt to the one mobile device to rule them all evolution or they will find themselves as a software company only (not necessarily a bad thing, Nintendo is all about the games not the hardware, they just had to make the hardware because no one else would). I can see most people not wanting to carry more than one device on them at a time and a device that games, e-mails, Facebooks, internet browses, telephones, purchases, shoots photos and videos will be preferred over a device that just games. A game only device will be relegated to a toy for kids who can't/don't need an all-in-one device. Still I expect 3DS2 and even 3DS3 will sell well. I think PSP2 (NGP) is the last dedicated Sony portable gaming console.
Expect to see a Sony Vaio Play tablet device in the next few years I suppose.
