Swery65's intriguing new game D4 will definitely be exclusive to the Xbox One, the designer has confirmed today. It's a pretty odd development for sure, but if you recall, Deadly Premonition was exclusive to the Xbox 360 for about three years in the US (it launched on PS3 in Japan-only before coming here eventually).
Our own Steven Hansen points out that when speaking to Swery himself, he mentioned that Japanese gamers didn't quite "get" Deadly Premonition like the US audience did. So maybe it makes more sense than we think. We'll find out if D4 can repeat the success if Deadly Premonition soon enough.
