Galaxy Nexus or wait?

I have my Nexus S which I love, but after seeing all of these new phones, but knowing once you go Nexus you don't come back. I'm looking at the Galaxy Nexus, but I know the new one will be released in November. I wanted to know if I should wait or go ahead and buy the Galaxy Nexus? If you guys could also help me out a little bit if you choose, if you can go listen to my friend's new song that I engineered I would really appreciate it.
