CUDA with C++/Fortran

So since it was announced that an upcoming CUDA version will feature C++ support as well as Fortran support I start to wonder what other features will be coming.
Does anybody know any other details? Do we maybe even get recursive functions to some extend?

Host code has been supporting c++ for quite a while.

I am well aware of that. I was refering to the announcement made recently at NVISION that presumably refers to device code. Photo of the slide can be seen here.

but… is it prudent to introduce new language features in the next release when the current state of the tool chain is still a bit far from being mature?
