I just tried to logon to my account and it was very long. It may be a hint that many subscribers are already downloading it!
The version I see from my account is “Visual Studio Team System 2008 Team Suite (x86 and x64 WoW) - DVD (English)” but I heard that the professional version is also available.
Earlier this month, Soma told that it was to be delivered before end-of-month and they succeeded.
