HDTV cameras are up to 2Mpix, full-frame at 30 or 60Hz. For a more down-to-earth example the Canon PowerShot cameras (from the 3.3Mp G1 to the 5Mp G5) have effectively no shutter lag if pre-focussed, and have a live LCD display at all times. If a 5Mp point-and-shoot can do it, I have a hard time believing it would be impossible on a DSLR.
