MS's main attraction is the motion sensing controls we can sure of that, and SONY's main attraction would be games that are catering to core gamers/casual gamers alike just like Little Big planet. But what about Nintendo? What is their main highlight of the show?
end of core gaming days prediction:
E3 2006-The beginning of the end. Wii introduced
E3 2008- Armageddon. Wii motion plus introduced. Wii Music. Reggie says Animal crossing was a core game. Massive disappointment. many Wii core gamers selling their Wii.
E3 2010- Tape runs out
