If the title didn't give it away, I regret to inform you that I didn't.
I'm sure everyone is aware that a long time ago I had signed up for writing a 3rd book.. A more "advanced" game programming book that took an already completed game I had written, disected it, and showed the techniques I used, etc. Once it became apparent to me that I wouldn't have the time for that, I left that project off in good hands with a co-worker and friend Rick.
Now, more recently I was asked about updating my quite popular Kickstart book with a second edition. The goal there being to add more content for the new API's, and update the book to the latest versions. At the time this was being discussed it was the early days of what would become MDX2, and I decided that should be the focus of this second edition.
So, both of these projects were designed to run with CLR2 and MDX2. As I'm sure everyone is aware now, MDX2 is evolving into the XNA Framework, which is delaying (yet again) each of these projects.
So, despite what Amazon says, to my knowledge there is no "new" Managed DirectX book coming out this week. Certainly not one from me. Plus, with the XNA Framework, a "Managed DirectX Kickstart" second edition doesn't seem as logical (second edition of a first run product?) so that seems likely to change as well..
