Square-Enix now owns Eidos

[A Black Falcon]

Eidos is a big publisher and developer, definitely. They owned Ion Storm, for instance -- Anachronox, etc. They also published for Looking Glass for a while -- Thief, for instance. And of course they have Tomb Raider, among other things. They also own the developer Crystal Dynamics (who made the last three Tomb Raider games, but did other stuff before then).

So... is it Square-Enix-Eidos now?

Probably just the Eidos division of Square-Enix, I'd bet. :)
