By my understanding, new trains of this scale/quality run around $1 million apiece. I don't think Cedar Point invested $3 million in their most popular coaster for no ROI (besides negligibly reduced maintenance costs) without releasing any information. They announced the new Maverick vests, I think they would've announced entirely new MF trains.
Plus, besides the Mega lites, Intamin hasn't manufactured the old style hyper/giga trains in quite awhile--Goliath/Walibi in '02?
The ones on Bizarro remsemble the old school hyper trains
