I bought a PS3 earlier this year - the first non-Nintendo console I've owned since the Commodore 64 - because the WiiU line-up was looking too sparse for my tastes. I'd only buy Mario Kart if I saw it for a bargain price, I played Wind Waker to death first time around ... the only *grabby hands* game for me right now is Smash Bros.
I don't judge it favourably from a hardware angle compared to the WiiU - I don't know if the PS4 improves on any of the issues I have with the machine (things like not being able to download games while the system is turned off, as the WiiU does, or being able to access the internet in the middle of a game, as you can on WiiU). It freezes a surprising amount. The controller's shoulder buttons feel like they are waiting to snap off. The slowdown on some game ... ridiculous!
Comparing the WiiU to a PS3, I'd say the WiiU is by far the better piece of kit. I really value the addition of GBA games to the eshop - along with the European release of Earthbound

- and they're far better to play on the pad than on the TV. It's also backwards compatible with Wii games, which for me is another really valuable trait.
But returning to the OP - I'd be lying if I said I wasn't feeling a little dismayed by the line-up. I'm hopeful about the new Zelda, but I didn't like Skyward Sword that much (do not want repeating bosses!) so I'm less excited that I would otherwise be. I'm *really* excited about the Xenoblade Chronicles X. I would really like to see a Harvest Moon (or Rune Factory) game (I'll settle for the GBA version in the eshop! I still want to get me that mountain cabin!). I'd love a sequel to Lego City - that game is BRILL.
I think a lot is going to depend on this coming year. It should have happened in 2014 but it hasn't. But, this is Nintendo and they play things close to their chests. Who knows what's going to happen in 2015? I have faith in them because the bottom line is they make great games I want to play.
