I don't know there's a lot of VR Troopers stuff I didn't even know existed or I did but didn't how much it got actually made until it got put on the internet:
The Cybertron pilot
the dubbed spoof made by the cast
PSAs
Next time on promos
So who knows it might have stuff we don't even know about. Though I'll be happy they just have commentaries for all the episodes.
Honestly that's only reason I'm debating whether to just get the single season sets or wait for the box set.
