Sony's booth at CEDIA EXPO never approaches its presence at CES, but inside the pillars surrounding its exhibit and announcing its presence it demonstrated a stacked pair of its VPL-VW1100ES 4K projectors using material stored on its media server. I didn't think these projectors were performing at their best (and having reviewed both the VPL-VW1000 (the predecessor to the VPL-VW1100ES and essentially identical in performance if not in features) and the VPL-VW600ES I can vouch that they are competitive with the best home theater projectors you can buy). But on music a Sony ES audio system did extremely well, even if the room was far from optimum for sound.
One piece missing, however, was the new VPL-VW300ES projector Sony introduced recently at IFA (IFA is the European CES--more or less). The VPL-VW300ES is a stripped down and less expensive VPL-VW600ES, eliminating such features as the dynamic iris and lens memory. My Sony contact indicated that the company does not intend to market this projector here.
