I finally saw this book at my LCS and the Legion stuff is all towards the end.
It's a cute little story a la "a day in the life of..." plus a characteristic Brainy flub that's kind of endearing. Nice pencils from Lee, no question about that. At one point he even has Wildfire remove his helmet to reveal a human Drake Burroughs.
He definately knows how to draw sexy ladies (especially Dream Girl and Saturn Girl together on the same page, and Phantom Girl is no slouch either!

)
His black and white sketches are nice too as are the rest of his drawings throughout the entire book. The man has talent, that's for sure!
Unfortunately for me this is a bit too rich for what it is, and the Legion's presence isn't enough to warrant the cost of the book.
Hopefully Mr. Lee will release those Legion pages as a backup to one of the current monthly titles, or even better, do a one-shot Legion comic himself and have those pages included as well.
We can only dream.
