What do u think ???

does any one know when is the release date of Agency? this year?

You left out gears 3 w/ natal functionality :)

I can't see how a premium PSN service will be good to dominate the show. I'd rather have infamous 2 there.

okay i added gears 3 :D

I love how Ninty's is not to release or announce new games in general, but very specific. Release a new Mario, hurry! Zelda! More just the way the op worded it lol. And no more peripherals please, just games. Oh and sony needs a GT5 release date for god's sake. And I think a 360 slim would have more impact, at least initially, then Natal.

nintendo doesn't need to announce anything really lol
but i really don't know what to add for nintendo

I'd like to see some more game announcements that utilize the M+ and Balance board. Be they "hardcore" games, "Gamer Games" or "Blue Ocean", I'd just like to see more.

I'd also like to see bundle announcements. A Balance Board/Wiifit/ Wii bundle, An M+/Sports Resort/Wii bundle, and some "hardcore" bundles. Maybe Prime Trilogy, Monster Hunter, Even a Red Steel 2/M+ Wii bundle.

By the way, do we know what Rare is working on? It'd be nice to see their project at E3.

nintendo only has to announce and show off DS2 and Shigeru in Link costume with some CGI trailer also Cammy in Samus suit/Reggie as Luigi would be instant WIN.

if we look at current announcements Nintendo and MS have the biggest chance to win E3 overall.
Nintendo already have:
- DS2 official announcement and DS2 games announcements,
- Zelda Wii trailer/live demo,
- Wii Vitality Sensor game and release date,
- Metroid: Other M live demo,
- 5th Gen Pokemon announcement(possible DS2 launch title),
- Golden Sun DS,
- 3rd party titles like Conduit 2,
- 2-3 completely new unknown titles for 2nd half of the year,
MS have 2 huge 2 hour long conferences at E3 - one only about Natal and the second one about rest of 360 related stuff so we know they will drop some huge bombs there especially with:
- final Natal announcements about games, pricing etc.,
- Halo Reach stuff,
- Fable 3,
- new Epic game(probably Gears of War 3) and maybe even Shadow Complex 2,
- new xbox live services like Hulu etc.,
- possible 360 slim,
- new Turn10 game(possible PGR5)
- at least 1 new Rare title,
- cross platform gaming they showed at GDC,
- Feelplus+Sakaguchi game,
- and probably tons of completely new xbl/360 titles and dlc deals,

Does anyone else think we are going to see another 2D game in an attempt to emulate the success of NSMBWii, Donkey Kong perhaps?
