I actually prefer the XBox One controller which is very nice.  Nothing on the PS4 interests me now, but I'll want to play Mass Effect 4 and Kingdom Heartss 3.  Mass Effect 4 I could do on PC if I used the money for that instead (which is tempting) but other multiplats will be late, or have crappy PC ports, plus I'm not all that tech savvy.

I should note that any company that announces Shenmue 3 or Mega Man Legends 3 instantly wins. 

Already own a Wii U and X1.

PS4 - Needs more top-notched exclusive games. Yes, we get it.. they have a history of awesome exclusive games. But that's what they're really lacking right now. At the moment, it seems like the only reason to buy a PS4 is if you want slightly more enhanced visuals for multi-plats.
X1 - Gonna be getting Sunset Overdrive, looks pretty cool. Still waiting on any Gears of War stuff. Would like to know more info about Halo 5, Halo 2 Anniversary, Quantum Break, and the new Fable. Hoping you guys have some new IPs in the works.
Wii U - Just waiting on both Smash Bros and Mario Kart 8. Would love to see a new Mario Tennis, Strikers, and Party (Please add online support for all these games). A new StarFox game would effin' awesome! More info and gameplay from Sonic Boom please.

PS4: Gran Turismo stuff. Either GT6 for the PS4 of the next game. I also want to see new IPs.

WiiU: Something NEW. I love the Nintendo franchises but I won't buy a WiiU for just the same series over and over again and for once SSB will not be enough to sway me.

Xbox One: Something that isn't a shooter, a kinectless SKU, and for the love of god let me use things like Netflix without a Live subscription. I don't play online enough to justify for a PS+ AND a Live subscription and I'm sorry but MS losses on that toss up.

Wii U: Already have one
PS4: 100 price drop and more JRPG games
Xbox One: 200 price drop, revival of some Rare IPs and some JRPGs

They would have to show gaming in a way that pushes the industry forward like we've never seen before. Right now, they're just last gen consoles with better specs, playing catch up with Steam. That's not going to cut it for me.

I honestly believe we won't see the "next big leap" until VR is a thing.

Well not exactly just because. I honestly wouldn't play it much if I did get it. I would never carry it around with me... I already have to carry my phone, wallet, keys... Don't really want something extra to carry just to game. I already have a PS3, PS4, and a decent PC that have plenty of games that I can play. I actually have several games on PS3 that I still haven't gotten around to playing yet. The only mobile gaming I do is on my phone and even that is quite rare. I just prefer playing on my TV or PC monitor.

WiiU: Xenoblade HD
Playstation 4: it's already announced, KH3
xbox one: only if something like khiii moves exclusively to xbox1 happens lol

I have all 3 but I would say what would be more impactful for me is if Project Beast is real and seeing The Last Guardian show up. On XB1 it would have to be something brand new I haven't heard of to show they are committed beyond Halo, Gears, Forza, and Fable. For Nintendo I would want to see more of X, want to see Zelda, and a new IP. I need something new from Nintendo that has nothing to do with their past franchises. A new IP from Nintendo would really surprise me. I know they are working one but I prefer to see to believe.

PS4 - Something really amazing. KH, MGS, and FF are all multi-platform now, and those were the only reasons I bought a PS2 and PS3. Maybe if an amazing RPG were to come out (Project Beast) or an FPS that doesn't suck, maybe I would buy a PS4. Also will wait for $299. Won't buy at current price since I already spent more on an Xbox One.

Microsoft needs to announce a Halo 2 anniversary that plays EXACTLY like halo 2. None of this stupid perks/random drops or loadouts from halo reach and 4. Just good old fashioned halo and if buy an X1 instantly. If not... well then I'll probably never buy one. Don't care about any of the other consoles.
