Thanks to FamilyGamerTV, we know that Crash’s Skylander figure will work on all versions of the game. This implies that Sony does not own the IP and that they are just working on a partnership for future Crash-related projects. Very interesting to learn about but at least people who love Crash on Xbox or Nintendo can use the figure on those versions. Crash’s Skylander figure is sold exclusive through the PS3/PS4 versions of the game at the moment.
Crash’s Skylander look heavily invokes Zembillas, the original designer for Crash, design in addition to being quite stylized.
