The Wii U is just not selling. Nintendo keeps saying that they're going to sell a bunch during the holiday season. I shutter to think what will happen if they don't. I really want to get one for Wind Waker HD, Xenoblade, and the upcoming Xeno game but the entire console might fail before I get around to buying it. Kinda worried.
Man, you're going to be in for a shock when the PS4 and Xbone are going to be floundering for the next year or so. Namely, because it takes a year or so for any new console to develop a library, a couple of killer apps, and an install base large enough to subsist on for the rest of the generation. And given the WiiU's upcoming price drop as well as the titles they've been readying for the holiday season, I think they're probably going to pull through comfortably enough (bonus points for not having much to compete with from Sony or Microsoft this year outside of their console launches).
I can't remember the starting lineup for the PS360, but things def aren't looking too hot for the WiiU as it currently stands (upcoming titles are mostly Nintendo's own first party stuff and a lot more love still going into the 3DS>WiiU it seems). If I had to guess, Zelda WWHDis being released earlier to prepare for the upcoming release of the next gen Fall consoles; at the very least,the timing is especially sweet (complete with a WiiU Pricedrop, Zelda releases, Pokemon X/Y, and 2DS).
If the PSP (and, atm, PSV), Wii, DreamCast, and even the GameCube to some extent proves that a system can certainly fizzle out, and while I think it's too soon to call the race for how well the WiiU is holding up, it's not holding a good hand of cards to play. Here's hoping they mop the floor at the Tokyo Game Show?
I definitely agree that the PS4/XBone are looking good solely for the fact that they look pretty... but their releases aren't *terribly* impressive at all beyond the generic lump of titles.
