I agree with this for the most part (the thing will still need 3rd perties, but not as much as the previous consoles). I love the Fusion idea and I hope Nintendo goes all the way on it. I only see one problems with your logic: Handheld games and home console games don't take the same time and resources to make. If Nintendo doesn't organise teir budgets and teams correctly, we could see them making too many handheld-like titles instead of the big home console-like ones. And that could annoy people with both models or the home console only.
Also, lol at the NX logo. Here's a free NX gif too.
