I read the raptor platform might stay the same thru 2015.
how many plants build f150's now days, and which one builds the raptor?
If the raptor is built at a different plant than bulk of other f150's I could see that happening. They did that in 2004, the regular f150 was updated, but the heritage and lightning trim levels both stayed the 2003 body style with 2004 model year, but they were built at the ontario plant, the other plants changed over.
If the bulk of the f150's all come from the same plant as the raptor, with the modifications they had to make to fit the raptor down the line, then I don't think they may go that route.
