I've read a few rumors of a native 4K lamp based projector from JVC this year. I think this is the right move for JVC. I say this because Sony is already there at similar price points where the eshift lineup is. 4K is a better marketing term that will sell projectors than pretty much anything else from an average Joe standpoint. I hope at least one model comes out to compete with the 385ES at around $8000. If JVC can do this while maintaining similar light output and contrast performance that the RS440 or RS540 can achieve than I think it will sell like hotcakes. For someone like me, 1-2 movies a week and that's it, I can't justify spending a premium for a laser light source when it doesn't really do a whole lot for image quality. So if keeping costs down means a lamp based unit I'm all in.
I'd even be happy with RS440 levels of contrast, but I do hope RS540 levels of contrast.
I know Sony's unlikely to make a big move after a significant one last year with the 285/385, but as mentioned I also keep wondering what Epson is up to and if their initial steps into the LCoQ tech will be furthered to include laser iris action, higher lumens, a 4K design or other refinement. I haven't seen the LS10500 in action. I've seen a 285 and after having JVC blacks it was not quite good enough there for me.
