I know that Amazon.com has been sending emails to people who pre-ordered my book 3D Programming for Windows telling them the book is going to be delayed until October, but it just ain't so. The book has been published and definitely exists, and Microsoft Press Project Editor Valerie Woolley sent me a "hot off the press" copy that I've been enjoying immensely.
Whadaya want? It's August, and people are either on vacation or working at half speed. I'm sure Amazon is still recovering from another major book release a couple weeks ago, and will start shipping my book shortly.
