Sadly enough, there are now rumors printed at the Guardian that Google isn't optimistic about Apple approving the app:
"Sources at Google familiar with its mapping plans say they are "not optimistic" that Apple will ever approve a dedicated Google Maps iOS app. Though the app is reportedly in development and should be ready to ship by the end of the year, the sources say their plans are only proceeding in "the unlikely event" that Apple will choose to approve the app."

"Apple unveiled the section, which on Monday listed ten free and paid-for apps, to spotlight alternative mapping apps for iOS in an effort to placate users over response to criticisms of its own Maps app. Apps such as the free Maps+ app, which uses Google Places APIs and Google Maps tiles to bring Google Maps back to the iPhone, and the £3 app Quick Route, which mashes Google's directions and locations database with Apple's Maps tiles, are noticeably absent from it, even though a Google source says they are the two apps that would give back many of the capabilities lost with the advent of Apple's Maps in iOS 6."
"Further, a source at Google told me the feeling is that those apps were purposely left out of the new section because they promote Google and its "superior product" at a time when there is so much bad blood between the companies over the continuing smartphone patent litigation (following allegations from the late Steve Jobs that Google's Android OS ripped off iOS). In other words, no matter how bad Apple's Maps are, the company still wants its users to move on from Google and forget about them. This doesn't bode well for the approval of an official Google Maps app, the source says."
