This image was posted by Playtonic last year, after Yooka's release. The central character looks a bit like , but the silhouette is different. Could this be a tease for the next game that nobody realised, maybe a character from Schell's universe?
Their universe expanding could possibly be foreshadowing a game set in space, as well as obviously an advert for hiring new staff to create said game.
Gah, I could speculate all day about this.
