Season Five is one of the weakest seasons of the show for me, really only a few a handful of episodes I really love. So, I'll be waiting for a discounted price instead of pre-ordering on this one.
That said...the video quality does look quite great in this trailer. There are some great shots, like that Unification one that someone posted in the thread. And, again, overall the quality looks so much greater in every shot. I watched a later-season DVD episode a few weeks ago, and I swear, it looked like the old VHS/DVD difference to me, especially the SFX shots.
