I've seen more than a few meentions of Super Mario Sunshine HD...
How would they do that without the sliding L/R buttons that the GCN controller had???
I'm curious to hear what people think...
I won't predict that E3 will be disappointing, but I will predict that people will be disappointed regardless...

Focus on tomodachi collection
Show more from thing we already know
WiiU remodel

My expectations:
Hints at a 3DS successor (ie GBA came out in 2000, original DS in 2004. 3DS 2011, New system 2015?)
-A new Zelda for the Wii U
-Majoras Mask remake for 3DS
-More footage and info about the new Smash Bros.
-New, 3D (think Super Mario 64, not Super Mario 3d Land) Mario Platformer for 3DS
-Few gimmicky accessories for the Wii U
-Few Special Edition Console Bundles, likely revolving around the new Smash Bros

That is if they show up. I would NOT get my hopes up even if they do, sadly.

- No conference
- No Zelda U
- TPHD/MMHD/MM3D
- Metroid 3DS

Bayonetta 2 will be ported to PS4 and X1, right ? Please don't answer.

I expect a conference, featuring:

-Tomadachi Collection
-Majora's Mask 3D
-Pokemon Z
-SSB Date

-Zelda U reveal
-X name and date
-Mistwalker RPG
-EAD Tokyo's second project
-NFC game
-SSB Date
-Metroid Other M sequel
-Another collaboration

and hardware redesign, could be either system.

To be honest, as long as they show off Zelda Wii U and give "X" a proper title and reveal more about it, that's probably all I'd need to be content.

However, obviously I DO hope that they'll reveal 3DS games for the 2nd half of this year and beyond, give a release window for both versions of Smash Bros., show off Yarn Yoshi and Shin Megami Tensei X Fire Emblem finally, another trailer and release window for Hyrule Warriors, and hopefully have at least one "surprise" game for Wii U that we don't already know about.

oh, and another HD game. Either Mario Sunshine or F-Zero.
