EDIT: And I really don't see why everybody thinks that Bethesda is the "bad guy" here. Sure, they aren't going about it professionally but I seem to remember Interplay overstepping their legal rights before, with BioWare. They decided to license the Infinity Engine to somebody without BioWare's permission (I must add the required "iirc" here).
