Given that more and more movies each year are shot in 1080p24 (Superman Returns, Sin City, Revenge of the Sith ... ), they wouldn't benefit from any higher resolution than 1080 anyway - what you see on your HDTV is the best it'll get. 1080 is a very high resolution, and perfect for home theater viewing - and I think 4K would be great for digital theater. UHDV is almost too much - people that have seen it in action have suffered motion sickness due to the extremely realistic level of detail.
In other words ...
With the rate technology is currently advancing i ask if its really worth being at the cutting edge of technology at this given time?
Yes. It is.
