Fuck, how did I miss this a few days ago? After ordering the Silver Case games, my literal next thought was "I hope they remaster FSR too." Killer 7 is a nice icing on the cake, though it's a little less necessary than the FSR one (Killer 7 still looks phenomenal on the Gamecube and PS2, while all we got in the west of FSR was the severely downscaled DS version).
Killer7 looks amazing upscaled in Dolphin. I'm more excited for a proper HD port of the PS2 version of FSR in English. The DS version was good enough, but pretty ugly. Being able to play all the Kill the Past games on one system sounds great too.
Are you guys sure this is official? Grasshopper's (English) website does not mention any of those remasters. You'd think they'd do a news post and update their projects section but they haven't done so.
