Relic is almost (or entirely) exclusively a PC gaming developer. Why would SEGA buy them and expect them to make iOS games?
I had no faith at all in Disney right up until they acquired Pixar and just let them be. Then they acquired Marvel and just let them do what they were doing and that gives me hope for their Lucasfilm acquisition.
So hopefully SEGA didn't buy Relic to turn them into something they're not. I assume, and hope, SEGA is smarter than that.
