Joystiq interviews MGS4's Ryan Payton: Seems it's staying PS3 exlcusive

wow. I guess that sums it up. I always figured it would eventually get ported. But, unless it bombs on the PS3, I don't think it will ever see a 360 port.

Also, what would define 'bombed' for MGS4? >1m, >2m?

I'd say,

Bombed = sales of less than 1.5M to 2M

Average = 2M to 3M

Great = sales > 3M
