Ok I was inspired by the MKZ getting replaced by the huntsman (which I find idiotic anyways, but anyways)
Here we go:
The MKZ stays on the EUCD2 Platform or CD3 or whatever for the foreseeable future
The MKS: This could change, there has been rumors of Ford moving the Taurus to a RWD platform in 2012..but for arguments sake, lets say this doesnt happen since Flex is a big hit and D3 Taurus Sales pick up..and the MKS stays F/AWD
The MKR: Huntsman based, shared with a Future Ford RWD car. Using the show car as its intended direction, I get this feeling that the car would be alot more sporty then the MKS...but if the Taurus does move to RWD, well MKS could become the MKR
Continental: Lengthened Huntsman platform. Serious Luxury car...think Lexus LS or BMW 7 series, but starting at high 40-low 50K price range and tops out at 65K or so.
The big variable is with the MKS and MKR...and if Ford decides to keep a large FWD/AWD and RWD plaform. We know the Huntsman is coming, but what is the justification for keeping a large FWD Platform around if they do? The only thing I can come up with is the Flex and Lincoln Flex, but they will only sell about 75K between the two of them a year.
