If they do a Destiny HD Remaster, I can see at least two of the clip show episodes (specifically, those that aren't important to the plot) being dropped, they'll use the Final Plus ending (as opposed to the original ending), and incorporate some of the TV Movie stuff into it.
Also, what episode did they retcon Shinn's family's deaths? They went through the following:
- Crossfire between Freedom and Calamity (original)
- Calamity only (retcon)
- Back to crossfire between Freedom and Calamity (TV Movies)
