I think that 3D will be around a lot longer than people think (or want). I predict that they will get to a decent glasses free 3D before we see things focus elsewhere. I mean, come on, that is starting to border on holograms that look solid, and who wouldn't want their own Holodeck in their house?
I do agree that they should be bumping up the resolution, but most people barely see the benefit of 1080p because their screens are too small. With 3D, no matter what size tv you have, you see the difference (good, bad, or otherwise).
fhw, glad that you are enjoying it.
