I have been holding off buying a bulb for my Epson 5010 hoping Panasonic would come out with something new. I loved my AE2000. I mostly miss Smoothscreen, but other things, like motorized zoom/focus and perfect panel alignment were nice too. This being my third 5010 after the first two had to be replaced, I would like to go back to Panasonic. This 5010 is having it's own issues too. it failed to start this afternoon. I had to unplug it to reset it. I am not a fan of Epson Quality Control, but their support is great.
I am tempted by the Sony 4k projector, but I hate to invest that much when I think much better things are coming soon, like the announced/retracted RED Laser 4k passive 3D projector. That is what I really want.
I don't see this projector making it much longer though.
