New Brevoort Formspring

Very excited about the things coming up in Superior Spider-Man, but I'm a bit confused by the Silver Surfer news. In the past, Dan Slott hasn't been able to write more than two issues per month - he had to leave Avengers: The Initative to do Mighty Avengers, and he needed to leave Mighty Avengers to do Amazing Spider-Man. So is he going to have a co-writer on Superior Spider-Man, or is it going down to once a month, or what?
