The news that Warren Spector's Junction Point was focused on the Wii version of Disney Epic Mickey 2: The Power of Two, with PlayStation 3 and Xbox 360 versions being developed by UK-based Blitz Games, may have led to worries that PS3 could see a bare-boned HD port. As Spector explained to Eurogamer.net, however, a 'virtual team' approach is being used to ensure that the HD version of the title does its more powerful platform justice.
Just recently, everything (cross-studio development cycles) caught up, so now we're running in lock step, making them simultaneous. If we come up with something in tuning the game at Junction Point on the Wii version we think will benefit the 360 and PS3 version, that gets integrated into the 360 and PS3 version. If the guys at Blitz working on the next-gen platforms come up with something that will benefit, it comes back the other way.
The power of the next-gen platforms allows us to do cool shader effects, higher resolution graphics, and more and better visual effects. It is the same game across all platforms, but graphically, the assets are not shared. We created all new assets for both next-gen platforms, so it isn't just up-rezzed stuff.
It sounds like Blitz Games will have the means to make good use of the PlayStation 3's capabilities, though only time will tell whether the end result meets these expectations.
