Nintendo will win because Zelda U will blow everyone away!

Microsoft.

Sony is looking real dissapointing right now.

No FFXV
No KH3
No Media Molecule new IP.
No GG's new IP.
Beast Soul's already leaked.
TLOU Remaster(Yikes)
etc

It will be a interesting E3.
Nintendo and MS have to show lots of games to still try to be competitive this gen.
Zelda U, smash, halo 5, quantum break, etc.
Sony, even with no mindblowing games can go well due to meaningless hype. And also can show uncharted 4.

It will be an E3 far better than last's year.

Sony if they reintroduce TLG and reveal Project beast as ps4 exclusive, on top of Uncharted 4
MS if they don't
Nintendo will "win" with its fans i guess?

What company will win?  Whatever company you want to win. 

So, are a Sony fan? Can you see the future?

Momentum is definitely with MS at the moment...i think in general most gamers who actually care to watch E3 are looking at MS at this years E3.

MS really needs some meaningful positive buzz around the X1. And to add to that they have been speaking about games, games, games for the last couple of months. There's been lots of rumors, whispers and teasers coming from MS or people who are close to them. Seems like they are set to have a big one and they need it.

Expecting a good showing from Ninty.

Not expecting anything from Sony really. Doesn't seem like they have much beyond what we already know.

Nintendo will no doubt.

The gamers.
