Although it seems like everyone is back on team fake, I imagine it's possible that we'll see this new tech being used in one way or another and I hope people keep an open mind about it.
People would like to point towards Wii U saying that gimmicky controllers cause failures, but their most successful platforms ever were successful thanks to the new gameplay experiences they offered.
The gamepad was an expensive yet safe venture which essentially brought the DS screen to the console which resulted in an expensive machine that wasn't outputting visuals noticeably better than the old systems while being over $300 the entirety of its life.
The shared library teased by Iwata would also lessen the need to sell the console at X1/PS4 levels and lessen the need for AAA western 3rd party support as long as they can keep partnerships and 1st party studios pumping out exclusive software.
Without 3rd party support they'll find themselves as a secondary/non traditional platform but the 3DS sales show that if the price is right then that could work. The Wii U didn't work since it was a secondary system at the price of a traditional system without Nintendo's full output, the shared library could provide just that and it's seemingly powerful enough to run major Japanese titles like DQXI.
I guess we'll see how things turn out. I'm open to "new concepts" as all of Nintendo's new ideas have provided entertainment or at least not being detrimental. Hopefully we don't need to wait till e3.
