I'd buy one. The game library is pretty amazing (for Nintendo 1st party), and after playing it I honestly see no need for Nintendo to ever make a new console (although they will since you know, they need to stay in business ).
I see.. four paths.
1. It is released, and everyone's happy.
2. It's not released, but something better is.
3. They're pulling a KARL/SALT and won't release any of it.
4. It's leaked
and no those aren't guaranteed to happen im just a psychic
