Nintendo will finally have something worthwhile to show off because their E3 shows generally SUCK.
Nintendo had a GREAT E3 show last year. Though, the years before that were not so good. This year should be even better than last year though because of all the 3DS stuff, the new system, the last gen. Wii games, etc.
I am very interested to see the NGP though god Sony please give it a proper name at E3.
Can't say I'm interested in NGP. It just looks like Sony is trying to ripoff a lot of Nintendo's ideas (touch screen, camera, AR, suprised it doesn't have 3D...lol).
Microsoft I hope you got something to show other than people riding elephants

I wonder how Sony will go about doing their show after the whole PSN debacle.
Ditto on the Microsoft thing. lol. And I think Sony will do fine as long as A) The Store is back by then and B) They talk about the debacle, but don't talk about it too much. C) have a bunch of cool games to show off.
I am hoping to see at E3...
* New GTA game announced
I read at Ign that a GTA game is unlikely to be announced.
* New Resident Evil game announced (Capcom one)
Very likely. I think there was even a rumor or maybe it an announcement of a new Resident Evil game. Plus they have TWO RE games to show off for the 3DS. I'm sure there will be one for the PS3/360 too.
* Price cuts for 360 Slim.
I haven't been keeping up with the 360 much, but this does seem likely to me. The Slim has been out for awhile now. Maybe they'll announce some kind of special Slim/Kinect bundle or something.
* Elder V, Metal Gear Rising, Uncharted 3, Mass Effect 3, Batman Arkham Asylum trailers & gameplay.
Elder V will def. be there. Ditto for Uncharted 3, Mass Effect 3 (even though its not going to be out till next year now), and Batman Arkham Asylum. I'm sure trailers & gameplay.
As for Metal Gear Rising, maybe. Konami has been pretty quiet about that game recently...
Oh and I agree with Kadratis. Its too bad about Valve. Disappointing that they won't be there. I want HL2 EP3 also. lol.
That all said, I'm looking forward to Nintendo the most. 3DS & etc. Though I am interested in what Sony has to show. I'm only sort of interested in Microsoft. Not sure if I'll watch Microsoft's conference or not...
Anyway, is it E3 yet?!
