-Color Light Engine
Mitsubishi's exclusive 1080p DLP® 6-Color Light Engine generates yellow, cyan and magenta directly for brighter colors, a wider range of colors and whiter whites.

Mitsu's own site brags about 6 color light engine on the 734 over the 3 color 5 segment wheel.

So why should we buy the new 735 model? I saw a 734 at BB and the pic was amazing. They didn't have a 735 on the floor and I'm worried that I won't like it when they deliver it on Monday.

Any thoughts?

i have personally seen the 2 sets side by side. The 735 was much nicer. The 735 was much brighter and had much better color. The 735 also looked a little thinner. I have also found u can get the 735 cheaper than 734. In my personal opinion the new models are much much nicer, remember this is only my opinion!!! My advice is to go to mitsubishi web sight and compare the 2 models.
