Wow. Come on people.
Its not as if upscaling anything will take the ENTIRE staff at SE to accomplish.
Hell, remember how easy the God of War team said the upscaling was? Taking X. X-2, XII for the PS3 should not be that much work at all. What might take them some time would be porting it over to the 360 as well.
Ether way, all of this could easily be accomplished without effecting the work being done on Type-0/FFXIII-2/FFvsXIII.
