What is the deal with the 4000 review:
"Panasonic is touting a new lamp design, with a stronger red component (better matches the 6500K standard), to provide that extra brightness in best mode. That lamp doesn't improve the projector's brightest mode's measured brightness, by any noteworthy amount. "

Followed by:

" The end result is that the PT-AE4000 gets a significant boost in lumens in best modes."

What? I wonder if I can put a 4000 lamp into my "old" (six months) AE3000?
