Just to fuel the hype here: From The Source himself on japan preview:
"Next week will be interesting for Wii software, as the release of Tales of Symphonia on Gamecube accompanied a rather large hardware boost . Given the size of the Wii user base a ~220,000 debut for Tales of Symphonia 2 seems likely next week, which could boost Wii hardware to 55,000 or 60,000 units. For this week, expect Wii hardware sales to be in the 40,000 to 50,000 unit range."
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
