Wii has the top version of Lego Indy AND GH: Aerosmith, along with what looks like a big debut for Rock Band. The "third party software doesn't sell on Wii" argument has to be pretty much dead, eh?
Also: 8 of the top 20 games come with a peripheral.
"[Our former customers] are unable to find software which they WANT to play."
"The way to solve this problem lies in how to communicate what kind of games [they CAN play]."
