Don't give up hope just yet on an Xbox 360 version of 3D Dot Game Heroes. It looks like the game's development studio, Silicon Studios, has nothing against porting the title over.
My Game Flash visited the studio last month and quizzed producer Hiroyuki Misawa on a number of issues, including the chance for a 360 version. Said Misawa of a possible port, "We can do it. Our libraries are multiplatform, so it would be possible to make it for 360." Asked if there are actually plans to release the game on 360, Misawa said, "It's up to From. We're a developer, so if there's a call to make it, I believe we can do it."
