It could be as simple as putting the right people behind it to sell the idea to the public. NVIDIA released the SHEILD as this kind of device but it didn't take off. I wouldn't be surprised if it came out that the SHEILD 2's cancellation had something to do with being approached by Nintendo.
No BC.

One person who leaked the NS has said today that it does have extra power but I guess we have to wait on that like always.
I would be shocked if there's another handheld that's not just a revision of the NS.
While there's always been a PlayStation in my house and I've always had a fondness for them* I do believe Sony and Microsoft are starting to go for too much blood with the PS4 Pro and Project Scorpio. We barely have 1080p at 60fps and now we're pushing towards a pseudo-4K? To me that's an even bigger gimmick than the Wii U GamePad was. I keep reading some people say that they're pushing too much to be like PC and I think that's right. I'm not saying they're doomed but it is a trend. Right now the NS trailer is pushing towards 11 million views on YouTube and is still the #1 trending video from yesterday so it seems to be taking off. It's clear from that trailer that this console is all about fun first and foremost.
About games don't forget about the smaller Japanese studios that'll be all over this thing.
*Totally looking forward to Crash Bandicoot Remastered
