Fire Emblem won't make 500K? I fail to see the joke. It lacks 50K and hasn't been released in Europe! Even without Europe it should make it!
Excite Truck shouldn't make 1M, that is probably right.
Cooking Mama should have a good shot. It lacks 260K, and sold 15K last week, and it won't stop selling a lot. I reckon it should make 1M.
Pokemon needs 130K and sells more than 10K/week, it is a definate.
