It's going to be close, but without an install base large enough to even do 2 million first week (since there's NO WAY it'll do 100% attach rate), and since Smash Bros has 50% sales compared to the PS3 install base, and I don't think FF13 will do 50%, I thinking it'll be Smash Bros. But it could go either way.
Also, without knowing how the Smash Bros series could do on a console that sells more than 5 million, one can't simply say "oh well FF's always outsell the Smash games." That statement is true, but since the FF games (on the PS2 at least) had an install base close to 20 million, while the best install base the Smash Bros had was 5 million on the N64. So this will be a very interesting comparison.
