I actually have been think along the same lines as your predictions... if the reviews keep as high as Fam did, combined with crazy hype... this game could be nutz... especially with it broader appeal, than say HALO... plus it WILL sell 2 million + in Japan... which is already giving it a 1.9 headstart.
LTD
Japan 3.5 million
NA 10 million
Oth 6.5 million
20 total- both NA and others could end up being higher than that.... I think 3.5 is the max for Japan.
psn- tokila
add me, the more the merrier.
