Which will sell more? COD series (PS3) or Halo series (Xbox/Xbox360).

I'll have to agree with Kowenicki. BOII will sell over 10 million easily while Halo 4 will struggle to over it. If it had 2 or 3 years of selling it wouldn't be a problem but a new Microsoft console release will probably stall the sales.
