I don't know if anyone has pointed this out yet, but I just remembered that Eric Schmidt teased the Nexus S at the Web 2.0 Summit last year. Most Nexus Prime rumors seem to point to October as a release date. The Web 2.0 Summit is being held from Oct. 17-19 this year, and Vic Gundotra (Social SVP for Google) and Susan Wojcicki (SVP of Advertising for Google) will be speaking there. However, considering neither of those Google execs deal directly with Android, its a slim chance they will announce anything Nexus related there.
Also, the Asia D conference is being held from Oct. 19-21, and Andy Rubin will be in attendance. Therefore, it may be more likely Andy unveils the Nexus Prime there.
