I agree, while the current incarnation of nvidia grid is acceptable in a 5-7 inch handheld, I think a bigger screen @ higher res will see all types of bottlenecks. I would be absolutely horrified to see the bandwidth requirements for 4k, let alone 1080p 60fps steaming. I find 720p @ 30fps to almost be a burden on my current pipe.
Gamestream from one room to another is by far the better of the two experiences however, if they could make that experience even more seamless, and universally compatible, it will be a staple. It's already consumer ready.
Given all that, I really do think nvidia/android has a solid shot at success. To me it almost seems inevitable the convergence of windows\PC & android gaming. Nvidia is pushing so hard in that direction, and they have enough weight in the areas that matter that I think they'll be able to make an impact. Their influence on the PC gaming market is undeniable, logic would suggest they could do the same for this platform as well. Looking back at the very deliberate steps and the progress in each step, pushing it out a few more steps the convergence is very fast approaching. Maybe within the next generation or two of tegra.
Will this shield game console be a success? Ehh... I don't think so. The games need to come, but if you were to ask me back in 2000 if microsoft could pull off a console I would have said no, hell I did say no. But it worked, and now they are among the top with sony and nintendo. It feels too much like, and is just a glorified computer for your TV to your average consumer. They need to be like.... "GAME CONSOLE" with publishers, exclusive titles etc. And then be all like "look what else you can do!" "but nevermind that, look at dem games tho!" They're doing it wrong by showing off the technology as the main selling point, consumers don't give a shit about that stuff.
I still think they'll eventually get there, just not this time.
BTW, where is the portable 2 announcement?? *anxious nerd rage*
