This is my preferred way of watching this wonderful story. Having it in chronological order on DVD would be great, but that wish is probably a fantasy. One can dream though!
I second your comment. For me, the chronological order's the only way to watch the films, as the numerous and lengthy flashbacks of #2 are both a distraction and an annoyance. Will we see a release of the Saga? I'd guess there's a decent chance, somewhere along the way of time.
