I can't see aston bringing out a follow on car, maybe if there was somthing to build on from the old car it could be done, but a new car would be just that, ground up and I doubt prodrive have the money to do that.
Hopefully the GT program will grow and some thing good will emerge from this shambles.
See lotus have backtracked from the extensive plans anounced a while ago and the P2 car won't now happen, What a surprise, but at least the evora lives on and has done quite well I think.
