Upconvert? I'm pretty sure these companies creating displays that have the abilities to go beyond our current resolution sizes have software formats to adopt the higher resolutions, much less the hardware. Mainstream, of course, is where it matters and this won't be around for a while. As with anything technology related, hardware is exceeding software by leaps and bounds now and is progressively increasing its lead.
BD-R/RE v4.0 are capable of 100GB. Given that most movies in 1080p don't even take up 1/2 the space available on a BD-R 25GB, double the size fitting on a BD-R isn't a problem.

Uhh, that isn't possible. >.< Diminishing returns at this point. Of course this is the reason the display is 70" and not smaller. You wouldn't be able to see it at sizes less than that.
