The powers that be at Intel, AMD, IBM, Sun, HP and the other leaders in multicore processor technology know that multithreading is not part of the future of multicore computing. In fact, multithreading is the reason for the parallel programming crisis. Fortunately, there is a way to design and program multicore processors that does not involve the use of threads at all (see link below).
Having said that, The biggest problem facing the processor industry is not the parallel programming crisis. The worst problem of them all has to do with memory bandwidth. As the number of cores continues to increase, memory subsystems will be hard pressed to keep up. The memory bandwidth problem is the real show stopper because it threatens to repeal Moore's law regardless of whether or not the programming problems are solved.
I suspect, however, that a correct programming model will open new avenues of research that may lead to a solution to the memory bandwidth crisis.
