what if the next nintendo console was NOT in hd?

[Reasonable]

Personally, I'd probably stuggle to get it. By then I expect every TV in my house to be HD, and having hooked up the Wii to one as a test, I have to say I wouldn't be keen - great games notwithstanding - to hook up an SD console to an HD TV.

In the bigger picture, it probably wouldn't matter a hoot depending on what else it offered and the games it had.
