I disagree. It will not make it obsolete. The buses did that years ago. IMO, the monorail is there for nostalgia purposes. The evidence is in the movement of the Mark V to Mark VII. Retro design. Additionally, I would expect that Disney would not invest in this technology when they can get the same thing for much cheaper in bus transportation. The current monorails wouldn't be changed because it would require a completely new infrastructure. They would have to build a tube system with maglev like technology. I can't see anyway they could take advantage of any part of the existing Monorail system. If they are not going to expend the current system due to cost, then they are certainly not going to rip and replace it.
