i thought MS would win it. Nintendo being number one in the poll is very surprising for me. 

Really? I've never seen MS win a poll unless it's "who should leave the console race". MS has been the most vocal, so they have a lot to live up to come June 9th. 

I think the reason that Zelda U, which we are 80% sure of seeing, is a guaranteed win for Nintendo is that we've not yet seen an HD Zelda.

Remember the difference between Halo 2 and 3; that is what is probably going to driving Nintendo hype coming out of E3. Or the first time Gears of War was shown off.

Then add to that hype, the NFC line, title and date for X, dates for Smash Bros and Bayonetta 2, more info on Sonic Boom; all things which we can confidently say we will get at E3.

And then there's the strong maybes: Yoshi Yarn, SMTxFE, STEAM etc.

And finally the unknowns.

Nintendo has a lot to show at E3. And in all likelihood a lot we don't know about.

I can't see Sunset Overdrive, Halo 5 and excuses for poor sales trumping any of that. Or any of Sony's offerings interspersed with crowing about how you don't need games to sell consoles (except in Japan :p)

Probably MS, they will of been buying up 3rd party games big style in the last year.

Sony will be relying on first party and exclusive marketing deals.

Nintendo will be just first party, great titles, but just more sequels of their big brands.

Cute. Fact is that both Halo 5 and Uncharted 4 are more likely than not going to outsell Zelda U.

For me the company will win which shows the most unexpected cool thing and so I can't make any predictions because I can't expect the reason why the winner will win.

Microsoft

Microsoft are good contenders. They have a point to prove, and I'm sure Phil Spencer has been hard at work to make it a great E3. They'll definitely be showcasing some great 3rd party content.

I'd say Sony stand the best chance with the PS4's current momentum. There's a lot of 1st party studios, Naughty Dog in particular, who haven't shown off their work. Let's just hope they keep indie and corporate talk to a minimum.

I can't really see how Nintendo could objectively win this. I'm sure it'll be great if you're a Zelda fan, but they don't seem to have the content nor an actual lengthy conference to stand any chance of winning.

*looks at sig*

You're definitely right about the sales though, but those are definitely not bigger franchizes than Zelda, lmao.
