You mean not until Apple releases there.
Seriously though, if they did a Retina Cinema Display in like a 40 inch with HDMI input I'd be all over it. Put it right next to my ODD list, slimmed up 30 inch retina iMac.
That would be great but there's no content to show on a screen that good, yet. Outside of using it as a giant external monitor there's really nothing to play that would take advantage of the resolution.
Hopefully the arrival of these screens will lead to higher standards arriving sooner than later.
