MGS4 won't outsell GTA4, or GTA3, or Vice City, or San Andreas.
The best selling MGS was the first one at 5.59 million, on a console with over 100 million sold. They've sold fewer copies each time. I'm not saying 4 won't outsell MGS3 or 2 or 1, but.... there's no chance in hell it'll outsell any of the GTA3s or GTA4.
