I doubt there'll be a "cure" at least in any of our lifetimes. Viruses are very, very, very hard to cure. Keep in mind we haven't even found a cure for the common cold. Every virus you've ever had you STILL have, your body has just managed to cope with it.
So I don't see a "cure" for HIV/AIDS coming anytime soon it WILL just be a way for you to "live with it" will just become more and more advanced ensuring longer and longer, even normal, life spans. The "best" we can hope for is a vaccine that'll prevent you from being infected with the virus in the first place. But a vaccine isn't a cure.
