At the moment someone with a very slow connection is uploading install.wim what we think may be x64 PRO (and able to be activated judging from some screenshots if from same source) the guy uploading is the same guy i think that leaked the ENT edition and its around 70% complete uploading. This is most likely EN-US also but no one is 100% yet going on screenshots floating about with pro English activated and pro English desktop it most likely is. Give it around 2-3hs for upload to finish and then wait for more public leak.
