I think you do. I have an xbr3 and I was at best buy the other day and saw the xbr 4 hooked up to blu-ray. It had Dead man's chest on it, and I have watched that on my xbr3 and I was surprised at the difference on the xbr 4. It is a lot more lifelike. I was surprised and mad that I didn't wait for an xbr 4
