They should scrap the PS3 version.

Irrelevant.

XI survived on the PS2 long past the life expectancy of the system.

Actually, it's not irrelevant, because XI is not surviving on the PS2 all that much longer- Support is gone in the US, and will be gone in Japan at some point after the new expansion comes out. XI tested and pushed the limits of the PS2 and can not grow or expand much more without leaving that platform.
