Check the Developer Console homepage; ensure that it says "Published" at the right (this is the same in both designs). If it says this, and all your fields are valid (as in, if you edit it, and hit Save, no errors are shown), you may just have to wait longer. My apps are usually pushed within 2 hours, but I've heard reports of it taking up to 23 hours. I think it just has to do with Google's server traffic (how many apps are waiting to be processed), and other factors as such. It's worth noting that the process is entirely automated once you hit Publish.
