The concept is great, but it works much better ala cross-buy like with Vita and PS3/4.

Unless the handheld and home console had very similar architectures, it would crazy to expect the same code to run on both systems. This isn't like a PC in which a lower spec'd machine can run the game at a lower resolution. In the hypothetical situation that physical carts can be swapped between the two, the most likely thing to happen is that each cart has two versions of the game on it. Not the biggest issue, but it does mean devs still need to make two versions of the game.

Also as I said in padib's thread, each system has different inputs. A wiimote/gamepad centric game just can't be played on the portable. What does Nintendo do in these cases? Not allow those games to be made?

A console as strong as the "Fusion Terminal" would be expensive to develop right?

This is basically what i wanted for some time now.
I just don`t know if other Nintendo portables could even be used as controllers. Probably just the new handheld.

Still, being able to buy one game and play it on both consoles (i assume both share the same saving process) - on the go or at home -is a great idea.
Being able to use them as one would be the biggest reason to own both seeing as we would be seeing a streamlined line-up shared by both consoles. Which would allow for Nintendo to use their human resources to build other kind of games, instead of having to develop, for exemple, 2 different Mario games, 2 different Zelda games, etc.

Seeing how Sony's foray into the Smartphone/Gaming console business ended, I completely agree.

Would I buy this? I'm not convinced if I like it yet. Does it sound like a good idea? I think it sounds very risky.

no and i'll tell you why.   this configuration would require developers to build two versions of every game.  the power gap is too large to "just drop resolution" and expect a game to run probably in both configurations.   this alone guarantees no 3rd party support which means fuck it,..  i'm out.

no I won't play it because it's a stupid rumor and fake

but as a nintendo fanboy yes i would i will buy any new system (2DS/Wii mini don't count)

I thought the same thing about the PS4 and look how well that sold.

I know what you mean, but "Fusion Terminal" sounds like it has specs to match or surpass many high end PCs.

I know Nintendo is going to be more aggressive with new products, but I didn't think they'd go this far. Would be very interesting if true.

1) game engines are very scalable now. If you had a high end portable with a non-high end home console... the game would look better and maybe have some additional features on home but still play fine on portable. Its all in the SDK between the two systems where it can be done.

2) Definitely NOT two versions of game... but one version that is scalable.

3) wiimote (using pointer/motion) is only issue. But I only included that for Wii and some WiiU BC. The new games would all utilize the gamepad/3ds button types. They would be identical in the new portable/gampad.
