They use some footage from ANH and ESB in the piece, and maybe it's just me, but things seem to look...crisper. Cleaner. HD...er. Especially the Death Star Attack footage from ANH.
Anyone else think it's something new, or is just old 2004 stuff? The explosions look 2004ish, but the ships and their animation appears newer to me.
