Nintendo is running mild this year several great announcements most for DS but several major announcements for the Wii as well.

Hardware

Wii motion plus- extends the precision to a near perfect level
Wii Vitality- a super pulse reader or something?

Games

Super Mario Galaxy 2- more of the same, little Yoshi action in it
Metroid other M- Nintendo x Team Ninja crossover, 2d and 3d elements great visuals, best E3 surprise from Nintendo 2010?
New Super Mario Bros. Wii- played the DS version this is better
Silent Hill Shattered Memories- this time around no gun, only u and your possessed I-phone, a port of the first one… mostly
Dead Space Extractions- prequel to Dead Space… Rail based
The Conduit- rail based and confusing trailer June?
Final Fantasy Crystal Chronicles: The Crystal Bearers- real time, air ship mini games
Wii Sports Resort- honestly better than I thought, has sky diving, archery, and swords July 26
Resident Evil: Darkside Chronicles- rail based story orientated, could be worse
Red Steel 2- nice sword action and can use gun anytime with the sword
