I found this 1997 PDS preview from an old video game show called Electric Playground. The preview starts at 10:50. It shows some odd things that I don’t think were in the final game. For instance: Radgam the old hunter from Zoah can be seen sitting on the stairs near Aldo’s house, the battle interface looks different and one of the Sega reps stated that the game was planned to have 100 hours of gameplay!
Here is the video go to the 10:50 mark:
