Heres a quote from our Russian friends:
First of all, we can all see what is really July 10, 2009, Microsoft made a choice between the candidates in the final RTM release: 
 6.1.7269.0.win7_rtm.090706-1900;  
 6.1.7270.0.win7_rtm.090708-1900;  
 6.1.7271.0.win7_rtm.090709-1520;  
 and as we wrote earlier, it was determined what the final build will build, he became the build 7600, build: 6.1.7600.16384.win7_rtm.090710-1945 
 Nevertheless, we venture to suggest that even today, tomorrow or on 13 July, Microsoft will collect another assembly (eg 16386) which will be provided TAP'am as well as possible is it to be announced at the upcoming World Partner Conference WPC09 Microsoft going-ment New Orleans (New Orlean) from 13-16 July, but July 24, this assembly will provide the partner of Microsoft for download from CONNECT. 
  In Asia (China) of the internet network already has the message and screenshots assembly 6.1.7600.16384.win7_rtm.090710-1945:

Also, there is a BETA1 of Office out there too. Much the same as the technical preview I hear, and only lasts 30 days before you have to activate it.
