I spoke to the high level manager again.
He told me he made a mistake before, but now he knows for sure:
Valley Fair is getting an RMC Raptor next year. The Wave will be removed, and the Raptor which will be named Mississippi Marauder will replace the Wave and the spot of the Riptide.
So that way when Park guests enter, the first thing they see is the Mississippi Marauder. Then later on, Dino's will be replaced by a front gate B&M, so then Valley Fair will have an intamin, gci, rmc, and b&m.
This also removes the water rides at the front (riptide, wave), so that all the water will be at the back.
