What protential game can challenge Wii Resort as the top selling game of 09

[Hephaestos]

I think GT5 will only go to 6-7 mil in the end, maybe 10M if PS3 goes to 40Mil.

WSR on the other hand will most definitely pass 10M in less than a year.

all wii gamers will get it and most casuals will have it on top of their list...
