I dont know if you know about his but NP has given SSBB a 10 out of 10. Many believe Brawl will not surpass Galaxy, or match it score. NP gave SMG a 9.5 out of 10! This means that SSBB is really worth it's hype.

I'm sure that SSBB will surpass Galaxy in sells as well. I don't know the current sells for neither SMG or SSBB but sure Brawl will be the best of 08!
