I can't make sense of that video. NVidia announced C++ support. You claim this won't happen? Sounds a bit strange to me, so I suppose this video is by people who spread too much FUD or something.
Every indication is that they won't release sooner than Q1 or Q2 of 2010.
Personally, I don't doubt that we'll see some form of C++ running on those GPUs. However, I believe this will be *far* from what C++ will look like on the CPU - I doubt we'll see stuff like multiple inheritance (or even single virtual inheritance), partial template specialization or any of the other features that make C++ more than C-with-classes. Don't expect to take your favorite C++ application (e.g. Firefox) and compile it for the GPU anytime soon (before Larbee at least).
Note that DX11 already supports C-with-classes, so Nvidia won't be bringing anything new to the table...
