all of the above but C++ can be used on the current hardware.
CUDA Fortran is already available in PGI 9.0-4 (public beta).

yes, indeed and such a strong skew towards HPC worries me. there is
almost no word how gamers are going to benefit from Fermi apart from
C++ support. in the mean time RV770 offers 2.7 TFlops SP and 1/4 of
that in DP which positions it pretty close to Fermi in that respect.
in RV770, quick integer operations are in 24-bit and i wonder if the
same still holds true for Fermi.
