I have his Mega Memory book, which is same as course (I guess). Most of the techniques are same as ones in other memory improvement books. No much new stuff. The only difference is his way of putting it together (which, by the way, is good) and exercises (which help you integrate techniques).
Search the forum for memory optimiser and you'll get the previous post where Pete described what the course will contain. It's not going to be the same as Kevin's course. I guess the two will go hand in hand great.
