I actually hope that Ady renders the finished audio/video in a lossless format, and sets it aside on a dedicated hard drive. That way, all he'll have to do is pull it back out and re-encode it depending on the specs for the latest home media format. Revisited will be in its final form when released at 720p, so the only way to see improvement at that point will be increasing bitrate and better compression techniques.
Had that been the case for ANH:R, we might all currently have access to an AVC High-Bitrate bluray copy. Resolution might still be at 480p (or 576p), but I'm willing to guess it would have improved upon the already beautiful and amazing DVD-9, complete with a 640kbps Dolby track, or perhaps even DTS. ;)
