We were floored by the amazing Ori and the Blind Forest from Moon Studios last year, thanks to a marvellous story, beautiful artwork, wonderful music, and excellent gameplay. Fortunately, it seems like we might get more of this goodness and according to Nerdleaks on Twitter (who have a proven track record), the sequel Ori and the Will of the Wisps will be announced tomorrow during Microsoft's E3 press conference.
Nothing is confirmed of course, but let's keep our fingers crossed!
