Will Halo 3:ODST be a big system seller?

[ajaghvajagh]

No, if this game was Halo 3, then yes, as that would be a sequel installment into the series and since that came out 2 years ago, I think the 95% of the people who were interested in halo bought a 360 by now, so MUCH of the same people will be buying halo odst
