It's a combined Windows / Mac tutorial.
We shot it last month, have been editing it for several weeks, and it was just completed. It needs to be mastered to a DVD, art work created, sent to the duplicator, etc, etc.
It might be a few weeks yet till it ships.
If you're in a rush why not purchase the current DVD? The difference between it and the new beta are not huge. You'll get a discount if you then decide to order the new one.
The current DVD is only US $10.
