Welcome to the light, Mike. I've been a member for a few years but lurk more than I post.
I'd hope that this is a ride vehicle that can accommodate families as Disaster currently does. Disaster allows families without the recommended restrictions (expectant mother, neck or back conditions, heart trouble, etc.) to experience the attraction together. As Universal continues to market towards families with younger children, I would venture to say that this would factor into the choice of ride vehicle utilized.
