Will there be 4K discs?

[Trader342]

Is 4K 4000P so almost 3-4 times better resolution than blu-ray 1080p or is it referring to resolution so only 2 times better than blu-ray's approximate 2K pixel resolution?

I know it is early but I might hold onto DVD for another few years if 4K is right around the corner and it's that much better -- pretty much reference quality. However it might be jumping the gun as Blu-Ray is the top technology for at least 5 years before people are even talking about 4K being around the corner. But we're hearing that they're already remastering Godfather + the classic Warner films in 4K, it's like these companies can already do it but are just milking the market as much as they can.

I will probably stick with Blu-Ray since I'm already in, and since it's the best available, but I am already thinking about 4K

How big can a blu-ray project by the way? Before it loses quality? Let's say I am sitting 8 feet away, could I project 120" and have great image? Or is it more like 100" is the max? Thanks for your help, nice forum!
