Eidos is now merely a memory, much like Midway, Brash and Atari ... what do you mean Atari is still around!? Anyway, Square Enix announced today that the Eidos reorganization is complete and the company has been reborn as Square Enix Europe, which we still haven't come up with a clever nickname for: Le SquEnix? Der Europa Enix? SEEurope? Eh, still working on it.
Update: Noted the brand "Eidos" still exists, even if the company doesn't.
