They hashed this out
over on NeoGaf and it's not entirely true. They are cutting jobs in Western publishing and the arcade division, and trying to keep those people employed by shifting them to open positions within mobile and online PC games. Some website exaggerated this as a shift of the whole company and it's not true. However, it is very likely that Sega will be scaling back its console endeavors, namely working with outside developers in the West to release console games.
A lot of people accuse Sega of mismanaging a gold mine of IP but the truth is very few people actually buy the releases of old franchises they vocally clamor for on social media. Even when Sega does release good games like Valkyria Chronicles or recently Alien Isolation, no one buys it and many critics even pan them. It's rough for gaming all around but Sega seems to be in an especially tough spot. We're still getting Persona 5 no matter what, so need to cause a big panic.
