Sorry everyone but I don't think this is going to happen.
I've already retailed some of the issues we've had in getting this tutorial out in a reasonable time frame. After talking this over, we are over 11 months past the release of Aperture 3 so the chances of recouping production costs on this tutorial before the next version comes out is slim.
I can try to answer application questions but I switched over to Lightroom at version 2. If you posts some questions if this forum, I'm sure we can get you some answers or best practises. I think Rounik might be an Aperture user.
We are sorry for getting everyone's hopes up.
