If I knew, I couldn't tell you. But I don't, so I can't. Personally I'm
hoping it's not for a long time, as I'm still working on a book about MM2
which is being published in December.
Microsoft doesn't tell me their plans and I don't ask. I'm under an NDA with
them and it's a lot easier to keep a secret when I don't know it.
Maybe you will get what you want with a minor upgrade rather than a full
MM3.
