It may be in a decent state to release on the PS3, but I'm pretty sure they're holding off anyway - as others have said, maybe until the next expansion, but my money's on when they begin billing.

Most of the reason they're holding off right now isn't so much about readiness as it is avoiding all the awkwardness would come with applying every patch to the PS3 version as well as the PC. Whatever happens, 'don't think we'll see a PS3 release until the development pace slows down some and the big changes are being delivered primarily through expansions, myself.

Not that I don't wish the PS3 version wouldn't hurry along and all.
