i suppose, although i did hear they was able to backport games, along with creating their own sdk rather then relying on Sony's leaked one. So hopefully that should head into getting an exploit soon. (considering they wouldn't do an exploit until homebrew starts to appear)
I don't know if it's changed in the last couple of days, but the sdk only supported C & not C++. I doubt there is going to be much homebrew in the short term because of this. My guess is that once they have homebrew then they won't release a new kernel exploit until all the homebrew runs on the newer version.
