It's Nintendo no contest. Is this a joke? Only one Sony IP has ever sold more than 10m. Gran Turismo. Ever. Like in all of video gaming. Even with the PS2 selling 150m+ units. Just one. Nintendo's last few IP's have sold in the 20's of millions. Wii Sports sold 80 million. Sony IP's sell the worst in the industry. Ever.

When it comes to sales, Nintendo 1st, Microsoft far 2nd, Sony absolutely dead last. You guys are utterly delusional. When it comes quality, Nintendo 1st, Sony a close second, Microsoft a closer third.

They all make good exclusives but the fact is, only Nintendo and Microsoft sell even remotely well. Sony is so far behind, you can't see them. The Vita is proof. Uncharted would save the Vita, right? Lol, okay. I'm sure Killzone will do much better. Even though it hasn't even hit 3m on a console.

When an Uncharted game sells better than Wii Party, then we'll talk.

I can't answer this any other way but Playstation and World Wide Studios. It's not even close, in my opinion. Just this year ALONE, we're getting/have gotten The Last of Us, Rain, Puppeteer, Tearaway, Drive Club, and Soul Sacrifice, and that's just off the top of my head. Freedom Wars and The Order: 1886 are on tap for next year. Just look at how wide that selection ranges, it's not like they're all confined to one or two genres. That's truly awesome.

Sony

Hands Down!

I wont even explain my reasoning unless asked

Ubisoft!

Those creative guys come up with new stuff all the time. They work with everyone on everything.

They are limitless.

i am talking about the big 3. ubisoft is french, so even if they dominate the gaming industry they wont ever be from the big 3

I couldn't answer the poll cause it's too early to be able to predict who would win this gen. And the OP has two major questions and the answer to both isn't the same to me. If they had to use exclusively new IPs from here on out,
Who would have the best exclusives? Sony
Who's exclusives would sell the most? Nintendo
But then there's still 3rd party content, so even if they had to stick to only new IPs from now on, it would be too difficult to predict who would win this early on.

i doubt they can ever do that again.

Sony, no doubt. Followed by Nintendo.
