The differences between the new TI chips are vitually none - at least no visibly. They have tweaked the chip slightly, and fixed anything that they found wrong with the previous year's chip. There is a big difference between the regualy '720p' chip and the new '1080p' chip. The DLP's that are 1080p use a method called "wobulation" (see S&V's explanation here) I wouldn't loose sleep over any of the minor differences between the HD2+, HD3 or HD4 chips that are being used. The TV's own processing engine will make more difference in the PQ than the chip will.
