All of my favorite GameCube games in HD.
ALL OF THEM.
(maybe)

Exactly.  The PS2 flew off of shelves at $299.  It's not too expensive at all for a new console launch, and Nintendo has already stated that WiiU will cost more than what the Wii launched for.  I think anywhere between $299 and $349 is almost a certainty.

OT:  Well, we know that all of the 3rd party games we already know about will be there in full effect (Darksiders 2, AC3, Rayman, etc), but I hope and pray for a surprise Bioshock Infinite announcement.  Also, we know that Rockstar won't be exhibiting at E3, but could Nintendo have secured a surprise announcement with the company for the press conference for GTAV WiiU?  I think it's possible.

Regarding 1st party games, we know about Pikmin 3 which should make excellent use of the controller, and the Chase Mii/Battle Mii/etc games from last year.  All indications point to some kind of Mario title at the show, and hopefully Miyamoto's new IP and Retro's new game (PLEEEEASE be a new Prime) will be there as well.

I have a feeling that Nintendo's E3 will be huge this year so, I'm hoping to see-

For Wii:
- Price cut to $99 effective immediately to extract the very last sales out of the Wii
- Kirby's 20th anniversary
- DQ X info (Though will be much more heavily Wii-U focused)
- Epic Mickey 2

For Wii U:
- Re-unveiling, with a new design and very possibly, a renaming.
- Pikmin 3
- New Super Mario Bros. Mii, possibly as a pack-in to really rack up the sales.
- Rayman
- Wii Sports U
- Unveiling of the system software and menus, showing off of some apps that will be available for it at launch.
- Wii Assorted Mini-Game Mix U
- Showing off it's online capabilities, with accounts, achievements and a Virtual Console that carries GameCube and Wii games.
- Wii Music U
- Retro developed Star Fox
- New console, new WarioWare.
- I actually think that Mario Paint is a real possibility, as a drawing game would be very suited to Wii U, and putting Mario on the box will heavily inflate the sales.
- Huge third-party reel.
- Mario Party X maybe?

DS:
Possibly mentions of Pokemon Black 2/White 2

3DS:
- Paper Mario 3D
- New Super Mario Bros. 2
- Luigi's Mansion 2
- Donkey Kong Land Returns
- New Resident Evil
- Animal Crossing 3D
- New Legend of Zelda
- Advance Wars 3D
- Big third-party reel

For both of the Eighth generation consoles-
- Description of what the Nintendo Network will mean for the coming years and their games.
- Super Smash Bros. early concepts discussion to build even more hype for it.

this seems very plausible actually. just add dq x to the wii u as well and were good

I wonder if we'll be seeing anything for MH3rd and FE there for the 3DS? After all, it's about time they get localised...

Well tbh... i never played any of the Trauma games. They never really appealed to me, so I don't really care about a sequel. However Advance Wars is one of my top favourite franchises of all time! I'd love a WiiU version! Though I do suppose a 3DS outing would be far more likely (I'd love that too).

And an Endless ocean in glorious full 1080p HD with tablet support for things like taking pictures would be  ecstatic euphoria x 9,000. 

Oh...don't make me imagine that...

Almost as bad as thinking of Xenoblade with graphics like the Zelda HD shown last year...or even just a Zelda like that!

I can't wait another 3 weeks!

I really hope they would announce a new F-ZERO...

I think Endless ocean on wii U is likely to happen at launch. Remember the rumors of it and pikmin running on "project cafe" at the beginning of last year?

Wait what...? WhatwhatWHAT??
