The local EB has new copies of the PS2 version Killer 7 for $10.

For those games on your watchlist, I wouldn't hold out too much hope for Samurai Warriors Katana, since it's basically a FPS version of Dynasty Warriors. Unless the formula is radically changed, those games have been getting bad-to-average reviews for the past couple of years.

Asterix at the Olympic Games? Oy. So we need two cartoony collections of olympic-themed minigames? I don't expect this to do to well either.

I expect No More Heroes to be rated highly unless it's really screwed up. There's a lack of mature and free-roaming games on the Wii (excepting the ports of existing ones form last gen like Scarface) and given the pedigree, I'm sure the fanboys out there will be gushing about it.

Nitrobike looks kind of generic, but there's a lack of good racing games on the Wii, and if it uses a control style similar to Excite Truck, it might do well.
