Is Blu-ray the End all, Be All?

[capitaltpt]

or rather, is current HD resolution the end all be all?

I'm well aware that the way the picture is displayed will change in the coming years with 3D, etc., but do you think we'll ever really see a home theater media delivering more than 1080p resolution go mainstream?

I'm aware that things like Quad-HD and Super-HD are in the works, but with TV sizes in homes averaging between 42" and 65" would a higher resolution make enough of a difference to become mainstream? I'm thinking not.
