Granted, my opinion on the "Fairlane" is based solely on pictures (as I would imagine are many BON members' opinions), but it appears to me that it is more similar to a minivan-sans-sliders than it is to a Pacifica type vehicle.
The floor appears to be lower than a Pacifica's and more similar to a minivan. Also, the squared off proportions will likely give the interior a greater sense of room.
I think the ultimately defining detail on how minivan-like it is going to be is the seating arrangement. I get the impression from everything I've read that it is going to have 2nd and 3rd rows akin to a minivan's.
Whatever it is, I hope it is class-leading!
