Maybe you are right. Its interesting!

Who made up this rumour? Neither are going to be held back for years after being announced for wii u. Very illogical.

These rumors are probably based on nothing and are purely speculation at this point.

well no
it is not fair for who like me just bought new 3ds.

they cannot just kill a new system like this X is ready - Zelda possible!

Nice FUD.

No.
For now we just know code name, more information about next year.

No, I don't really think they would do that.. these games are mainly to push for more Wii U sales

Definitely not.

Nintendo has made it clear that the Wii U will be their main focus in console gaming for the moment. This is Nintendo's first HD Zelda and Xenoblade X is Monolith soft's first true HD Xeno game. I don't think they're working on how they can port a game they've been working on for 3+ years if they haven't even released it on Wii U yet. Still, all this talk about NX is pretty exciting because unlike previous Nintendo consoles, we really can't predict this one. It's a total guess right now.

Backwards compatile with Wii U? Hahaha! Nope. It's insulting to Nintendo to claim they'd go with PowerPC yet again. Ports however are highly possible, I'd go for it if I were them.
