Still new to Marvel comics: a question about releases months

hi boyz and girlz!

as I said in the object, I'm still new at the Marvel Universe and Marvel comics in general.. But there's something I cannot understand about their releases.. I mean.. let's take for example the new Deadpool series (the one from Marvel Now! relaunch): here is reported as an issue of January, 2013, while this book is already been reviewed and it seems it's already been released just few days ago!!

Please can someone explain me why that? I mean, here in Italy if a release has to go out on November it's easy that it will be released on December!, not for sure on September!! :D :D It's a joke, naturally, but I'm sure you know what I mean..

Thank you very much!

see ya! ;)

I think cover dates are two months or a month over the release date.

Yeah DC and Marvel both use that system, i think it is because when there is trouble and they are late with the publishing, no one can complain because the date on the cover still says it will be out in a month or two. And we list the comics matching the date on the comic.
