Naughty Dog’s Christophe Balestra has told Ars Technica that technical hurdles would prevent an Xbox 360 version of Uncharted 2.
“First of all, we fill the Blu-ray 100 percent,” he said. “We have no room left on this one.”
Drake’s Fortune used 30 percent of the PS3’s SPU and Among Thieves used 100 percent.
Also, Sony is the publisher and pretty much Naughty Dog’s Lord and Master, so it would have never happened anyway.
