Thanks for your posts, sarangiman, I'm definitely following with interest.
For what it's worth, I am upgrading from an AE7000 and I always felt that the focus was off in areas.
I ended up using the focus test pattern that is on the Disney WOW disc to confirm and it clearly showed that the left side was out of focus. I actually had the optical block replaced, and it seemed to actually then make the left more focussed than the right! There is definitely a problem. Unfortunately I wasn't aware of the NEC pattern at the time but it would have really helped demonstrate the issue clearly.
On the AE7000 ghosting made 3D unwatchable, which is a shame because it was one of the main reasons I upgraded from an older Epson.
I viewed a HW50 yesterday after reports of its inferior lens but to be honest I was very impressed with sharpness, coming from the 7000. So your post above is very relevant to me. I was also very impressed with the 3D. Definitely some ghosting on tricky scenes in comparison to a DLP I viewed as well, but way better than the 7000 ever was.
Out of interest, are you looking at selling you HW50? I've narrowed down my choices to the HW50 and RS46. I'm still waiting for reports on the 3D on the JVC, but my expectation is it won't be great. The HW50 is looking like the best all rounder so I'm interested that you're potentially looking at replacing it.
