I don't think that's correct. I believe Ford will be building Shelby's in 2015. For starters the GT350 I believe will carry that name.
You may be correct and I stand corrected. It was rumored in Road and Track that Ford was going to drop the Shelby name from future GTs and just call them SVT Cobras. (www.roadandtrack.com/go/future-cars/spy-shots-2015-ford-mustang-news-and-hot-rumors) However I read that Carroll Shelby signed a licensing agreement with Ford for future cars just before he died. Of course you can buy a 350 and upgrade it at the Shelby plant in Las Vegas.
