Is there a particular reason to prefer 4...e6?
I always preferred 4...e6 as it avoids the line 4...Nc6 5.Bb5 e6 6.Be3.
After 4...e6, 5.Be3 can be answered with 5...Nh6 (though I have no idea if that is the line suggested in the new book).
I know very little about the CK, but am interested in this book following Scott's review in a related thread. But on the lines discussed above, I wonder if the author considers 5.Qg4 which John Watson gives a '!' to in his Mastering the Chess Openings Vol 1, where he gives some very brief analysis of this 'apparently untried' move. And in the 5...Nh6 line he thinks White has 'a solid advantage' after 6.c3 Nf5 7.Bd4 Nc6 8. Nf3 Qc7 9.Bb5, although he adds that Black can probably improve but is likely to still fall short of equality.
His verdict on 3...c5 4.dxc5 in the CK Advance is that White's extra tempo outweighs black's 'pleasant pawn-structure'.
Watson himself doesn't pretend to have given a theoretically accurate summary of these lines, I should add, but rather some guidance that should be 'helpful for the student'
Although I like the idea of trying out the CK using this new book (and I'm a chessbook junkie), I'm also slightly hesitant to start off with a repertoire that may be theoretically difficult in the hands of a lowly newbie such as myself. Incidentally, JW also painted a less than appealing picture of the move 5...Nc6 in the Panov - I'm sure Jovanka is adept at playing these lines but how well are they holding up in general, and are they explained well enough for a newcomer to the defence to play them well? JW thinks 5...Nc6 requires Black to play more accurately than White to try to achieve a draw, which he thinks explains most people's leaning towards 5...e6 instead.
I may still buy the book, as it sounds like a good way to structure an opening book, but it would be interesting to see if these couple of repertoire choices are explained/justified over what appear to be the more well-worn main moves.
