It does not matter whether people like a hybrid approach or not. 
There is pretty much no alternative if you want to use accelerators in a
cluster environment (GPGPU, Cell, Clearspeed - they all use some sort of
threading; but no, they do not use OpenMP just yet). 
And it looks to me that a many-core is more akin to an accelerator than
to a processor in that a new programming approach is required.
I'm afraid we cannot get away in the long run by using only MPI.
