That would make things a lot simpler. In my opinion, the mac office is a crippled version of the one for Windows. I have enterprise on my PC, which has so many useful programs. Now, on the mac, I couldn't even get half of those. Just the absolute necessary ones.
I think MS does it on purpose.
considering that it was 4 years between major updates (Office 2004 was the last major update before 2008) i doubt a major release will happen by september
