Yes. Yes it is.
We had 2 Zelda games for the Wii, it's time for the next generation. NES had 2, SNES had 1 (odd gen out), N64 had 2, Gamecube had 2 and the Wii had 2. Yes, the GC and Wii shared Twilight Princess, but I think the theory stands: Two Zelda games to a generation before the next gen. But more than that, all the perks that came with the Wii - Virtual Console, motion controls, etc. - have lost their initial this-is-so-new-and-cool luster, and it's about time for the Wii U to take the stage and show us why that weird controller/screen thing is in fact a really, really cool idea.
The PS3's much touted Cell Processor - did anyone else immediately think of Blast Processing when they heard this? - and its 6 cores is now being handily beaten by modern, ultra-efficient quad-cores, and that's before mentioning AMD's new 8-core CPUs. Also, some of Sony's half-baked ideas - the PS Move comes to mind - can be better fleshed out into controls that finally break from the same design they've been using since the first Playstation. Yes, the Dualshock is a great, simple design that works just fine. It's also closing in on 15 years old, and it's starting to smell like an old man, if you know what I mean.
The 360... well, new hardware might better support the Kinect. There's a LOT to say about the Kinect, but I still absolutely relish the idea of playing a strategy game with hand gestures. Improved networking hardware is always good for the Xbox Live system.
