To be honest, I can't remember any of them, because I was just disappointed that this one wasn't included on the list.
I think maybe the FFV part 2 was on there - they joked about how it was split up into parts so it would release faster but despite that, it's still been a very slow release. Also, maybe another Heroes vs Villains one, and maybe another one for something like MAGFest. I think there were four or five on the slide, but honestly I could be wrong about all three of these guesses. Their panel was early in the morning after a long night.
