not gonna happen

Oh gosh, that's totally ripping off Sony's idea. But a good move nonetheless if it's true AND at no cost like an excuse to apply a subscription based service.

Not for this feature alone. The exclusives are interesting, but they don't justify the New 3DS' s price in my opinion. If this is true, which it probably isn't, it would be a nice gimmick to try out and it'd justify the price a bit more.

If anything, Nintendo should allow 3DS games to run on the Wii U, whether through a "3DS player", or though technology inside the housing on one or both of the systems.

Maybe they wanna drop the gamepad. Would make sense, because the N3DS has the extra buttons and the NFC reader. If it's able to stream the games, then it can do everything that the gamepad can do.
Also the Wii U needs a pricecut badly.

Think it can be a substitute for another gamepad if games will start requiring two (Seriously I just checked that gamepads are still not sold seperately!) 

This way you could have 2 player off-tv play

Exactly what I was thinking.

Text in PS3 games was very hard to read when I used an SD TV in the beginning, and the 3DS screen is even lower res than SD.

My guess is if they do do this it will work over the internet.

They may be testing the waters to see if fusion is something people would want. No real other benefit for them to gain unless you count double dipping. 

I love my Vita, but playing PS4 console games on the Vita defeats the purpose. Smaller screen, more difficult control methods. I much prefer playing native Vita games.

I wouldnt use it on my 3DS with Wii U either for the same reasons. The new 3DS at least has 2 shoulder buttons though.
