The GPU won't be a problem since it's already supplied by AMD. Problem is the tripple core PowerPC 750 CPU. However, the CPU is based on gamecube era tech. A modern 14nm APU with work by both Nintendo and AMD would be able to make emulation possible. Especially if they use HSA to lift some work on the CPU part.

I'm not sure, but don't you have to pay for PSNow. Not really a great solution to BC.... Paying a subscription to play games you already owned. Not that I would care that much if Nintendo took a gen off of BC to boost hardware power. 

It's a different take on BC. One that will allow BC to come available in a console at launch without a lot of complications. May not be that consumer friendly but who knows. Maybe when Sony get back on their feet. They'll make the whole service free, part of PS+ or those games which you previously owned can be streamed for free. It's a very future friendly BC strategy.

That you have to pay for now. It's probably a great plan for people who didn't own a PS3 too, but it still kind of sucks to pay a fee to play games you already own. Granted, the alternative could always be drag the old system out and hook it up to play old games for free, but still a bit of a hassle.

I'm 100% sure the system will be BC, at least digitally. But I also doubt that they would have digital BC and not have physical, so it's all staying.

Nintendo isn't going to recreate the VC from the ground up for a third time. That would be a complete waste of resources, especially now that it supports the GBA and DS. All eshop games will be available on the NX from day 1. They are just spending way too much time on these platforms to just ditch them all and start from scratch on the next platform. It isn't happening.

And that's a good thing. The NX will launch as a system with Nintendo's entire legacy represented to some capacity day one. I don't even think of it as BC. It's what PC has been doing for decades - it's infinite legacy support. That's why BC with the Wii U and 3DS are important. Not disc BC specifically, but digital BC.

I've said it before and I'll say it again. Ninty has what it takes to make the NX an extremely successful console, but as time goes on, it seems like their approach will repeat a lot of the WiiU's mistakes..

Microsoft managed to emulate the six threads of the Xenos CPU inside the X360 on the six Bulldozer cores of the X1. I don't think there will be an issue to emulate the three threads of the Wii U CPU on Zen, or whatever AMD comes up for their APU.

oh how come i missed it? so i can put in a playstation 2 disc in my playstation 4 and then play some old classic games? ^^

It has been 2 years since PS4 and XboxOne released, if Nintendo goes with AMD, I really hope it doesnt pick an APU that much less powerful than the one they other have, which will be really a shame. NX should have at least about same calculation capability if not more than the other two.
But if Nintendo takes the approach to emulate old games by software emulation, I would speculate NX to have maybe a better hardware, which is what I like to see.

It'll be great as long as it isn't hardware based where we see it rise the price of the NX's hardware or determines its architecture.
