I think it will probably have similar first week sales to DMC4. So I think it will sell between 250,000-300,000 copies its first week (software).
I don't think it will move much extra hardware though...maybe 10,000 in the US. You may have a few ps3 fans that buy a 360 for it if they loved Sigma...but most of the previous xbox owners that played NGBlack have already gotten 360's by now. And NG isn't a big enough system seller for them to just go out and buy a 360 all of a sudden.
