Vita
Gran Turismo 6, a price cut to $149, and a couple good JRPG exclusives. Right now I'm only really interested in Uncharted & the Disgaea remakes; I need more then just that.
3DS
What I wanted was a 3DS XL in a decent colour, and an upgraded battery. I couldn't hold out after the solid black 3DS XL released. Fire Emblem & Pokemon really pushed me to buy the console.
So far I'm loving it. Best Fire Emblem ever, and possibly my favorite handheld ever. Pokemon is great, DS games look & play great, plus I'm looking forward to Bravely Default & SM 3D Land. I needed a 3DS because my DS tends to freeze when I move it around too much, and I always play on he go, so that's not good.
WiiU
What I want is a good console bundle. I was very tempted to buy a WiiU last fall, but I didn't care about the Mario Bros or Zelda Bundle. Had they still sold NintendoLand Bundles, I might have reconsidered. I likely will buy a WiiU in 2014, but not until they make a good bundle. Mario Kart 8 & Monolith Project X look great too.
PS4
Time mainly, why buy a PS4 when they still make so many great PS3 games, and when my PS3/360 backlog is so big? I had a bad experience with 1st gen Sony consoles, so I probably won't get one for a year or two, not until reliability improves, and not until games like Uncharted release. However with GT6 just released on PS3, and stuff like Drakengard 3 on the horizon, I just have no reason to upgrade so fast.
XBO
A Kinect-less console, a price <$249, and some games which I find interesting. Not into Halo after Bungie left, not into Gears after 3 concluded the trilogy, not into Forza after some developer decisions which I don't agree with (free upgrades, cars racing at identical PI, and never stock). So I'm going to need stuff like Lost Odyssey releasing on XBO before I buy it.
Say those games never come, I'll still likely get an XBO for Halo, it's a good co-op game. However if the games on't get better (multi-platform games don't count since I'll get a PS4 first), then I probably won't get an XBO until the price drops to <$149.
Gaming Spec PC
Got one cause my computer was over 10 years old, and struggled to play 720p movies. I mostly wanted something capabe of 1080p videos, and while I was at it I bought a decent graphics card & processor. So far I haven't played muc more then Starcraft 2 & SimCity, but come Titanfall, I think I'll really enjoy it

So far I really enjoy my 3DS, and my PC is nice too.
