As well as a remaster of The World Ends With You, a new edition of Tropical Freeze which lets you play as Funky Kong, a Mario Tennis title if that's your shtick. Lotsa good stuff announced ^_^
As well as Switch, the Dark Souls remaster will also be coming to XBONE, PS4 and PC. The xbox edition will apparently be at true 4K resolution, though this probably belongs in a DS thread. Do we have one of those?
