Probably not and probably not. Simlar issue: you'd need some SERIOUS compression or have to really stretch the disc's capacity.

Doesn't really matter, since the 1080P infrastructure is only just being developed AND when you think about it, film is only 24p anyway, so upconverting it to 1080/60p makes no sense. This will only be a real factor when there are thing shot in video at 60p. Some of the new cameras being purchased by CBS for Television City in Hollywood are 60P, but that's just for the future -- none of the rest of the infrastructure there is 60p.
