The problem with 3D is that so much brightness is lost through the 3D glasses that PJ manufactures have been upping the lumens output, but that makes black levels worse, unless they increased contrast performance by the same amount. That hasn't really happened with DLP or LCD, and LCOS tech has enough native contrast to spare, but it seems that once the JVC's (and maybe other LCOS's?) lose some of that new lamp brightness, they start to get increased 3D ghosting effects.
So 2D is still great with JVC's, but DLP/LCD's don't seem to be making any strides in 2D performance, and if anything, seem to be taking a step back due to the brighter (for 3D) models that sacrifice some of that black level to make up for the brightness lost in 3D mode.
So my guess is that the W7000 isn't gonna be any better for 2D than the W6000. In fact, the first user measurements on the Mits HC7800 showed it had WAY worse native and ansi contrast than the HC4000, though those measurements have yet to be backed up by others.
