From Fashionologie:

As is to be expected, this year's September issues are not going to be the behemoths of yesteryear: publishers are approaching their closing deadlines this week and said that they expect issues to be about a third lighter than years past.

The September issues are still anticipated to be the Fall's largest, as most advertisers withdrew their pre-collection ads that run in August to focus on September and will run fewer ads, if any, in the remaining months.

As for the cover faces, magazines are sticking with safe bets - blonde white women.

Vogue- Charlize Theron
(who usually graces their October covers in 2004 and 2007)

W- Kate Moss by Mert and Marcus

Elle-Jennifer Aniston
The “perenially newstand-friendly” actress.

Allure- Amanda Seyfried

Glamour- Jessica Simpson

Marie Claire- Ashley Olsen
(Who wants to be out of the limelight and stop acting, unlike her pap fiend other half. Great strategy Ash. Get a cover whilst not promoting a movie-- a la Lohan-- That will make your fame fade away.)

Vogue Paris- In speculation (Lara Stone?)
”Is said to be breaking the blonde mold by dying a usually flaxen-haired model's coif black in a "radical model makeover" - some suspect the "luscious" beauty in question may be Lara Stone.”

Vogue Italia- In speculation
”There were several compelling mademoiselles on set for that issue but Hiss Squad Milan is whispering that VI Sept 09 is a multiple cover extravaganza with some of those choice beauties going stand-alone. Now the fun part is sussing out who those might be...think compelling blonde (or two) weighed against a surprisingly unique choice of a brunette...I bet the kids will nail it with precision.” (via The Imagist)
