Friends with Kids trailer surfaces

Might as well be a spin off of Bridesmaids except the couples are a little flipped around. Kristen Wiig is with Jon Hamm and Maya Rudolph is with Chris O'Dowd. The film also stars Adam Scott, Edward Burns, Megan Fox, and Jennifer Westfeldt.
The basic concept I gathered from the trailer is Maya Rudolph and Chris O'Dowd are a married couple who have been married for a long time, Kristen Wiig and Jon Hamm are newlyweds, and Adam Scott and Jennifer Westfeldt are friends. The friends decide to have sex once to try and get her pregnant. It works and they agree to have the child while remaining in a platonic friendship. They both meet other people after the baby is born which is where Edward Burns and Megan Fox come into the picture. Every other cast member keeps wishing them luck and awaits the outcome of the situation.

To me this looks like 2012's version of Friends with Benefits/No Strings Attached only with a baby involved. I love the cast, minus Adam Scott and Megan Fox, but it looks too familiar for me. This is a maybe.
