At this point, I'd be surprised if Google resubmitted it. The reason being that I feel that the deep integration with Google Voice that Android phones can offer is a fairly good selling point when one hesitates between Android and iOS. (when it was initially submitted, Android phones were much less popular) That being said, if the unofficial apps get popular, it might then be in Google's interest to offer their own to control the offers and make sure their service is appealing to even iPhone owners.
