When I picked up a WiiU, I also picked up Arkham City, Black Ops2, AC3 and Trine2. Multiplat support seems fine. Nintendo seems to have non-disclosure for anything beyond the end of the 6 month launch window. I suspect this is intentional to give the launch titles the limelight for a while as a reward for early support, and so that E3 after the window ends will be a big explosion of games excitement. It's hard for multiplats to make money on WiiU with the small install base, so you're not going to see all of them ported. But porting isn't that tough, with Ubisoft saying it was pretty straightforward and cost about $1mil. Reggie's comments suggest that GTA will be coming. I would also like to see Final Fantasy, Bungie, Konami and Capcom support. If WiiU gets that...and I think there is a good chance for some with what will likely be a large Japanese install base... I would be happy enough to not consider another system. At least for quite a while.

What 3rd party PS3/360 exclusives are coming out in 2013?

err......(thinking hard)

I'm sure there must be a few indie ones, at least, but I bet that any major 3rd party exclusives we'll be seeing next year will be on 8th generation systems.

PS3

Tales of Xillia, Ni no Kuni, Atelier Ayesha, Hyperdimension Neptune Victory, Disgaea Dimension 2, Final Fantasy XIV, Blazeblue Chronophantasma, Kingdom Hearts 1.5, God and Fate Revolution Paradox (so far)

X360

Don't know, Xbox fans take it from here...

Well. I guess there are a few, heh. I was sure that Tales of Xillia was already out over here, but i guess Namco is still absurdly slow to port their Tales games over. -_- Besides Atelier Ayesha, I haven't heard of any of the games on that list, and I somehow forgot about Ni no Kuni. 

FFXIV is also on PC, though.

Based on that list, it's already over. Only two multiplat games being released on a console that currently doesnt have any captivating software to justify a purchase? Yeah...its over.

This is why people don't like nintendo. You release a subpar console, with subpar hardware and lack of software support & then expect people to cater to you? Why would developers cater to nintendo at this point? They didnt cater to wii when it was a massive hit, why would they bother. Clearly that list says it all.

Didn't nintendo claim they were going to have alot of 3rd party support, where is it?

ZombiU, Assassins Creed III, Batman, FIFA, Darksiders, Rabbidsland, Tank!Tank!Tank!, Trine 2, Little Inferno, Mass Effect 3, Black Ops, Sega Racing Transformed, Just Dance, Tekken Tag Tournament, Skylander Giants, Warriors Orochi, Epic Mickey and some more came out all in one week.

And that isn't even the half of it.  We don't even know what they may be planning.  I DO think WiiU WILL get more support than Wii, if not up to the level of PS360, at least better than its predecessor.

I do wonder how many times I'm going to have to quote myself in this thread.
