Hmm, I hope you're right.
In any case, google hasn't confirmed to be working on a google maps app either, so it's not even sure they'll make one, let alone that apple approves it. I assume they got paid by apple to have them use google's data in the iphone app, with that source of income gone, do they have an incentive to make this app for iphone? Maybe they'll try and market their superior maps program as a distinguishing feature for android.
Of course they did make a google earth app and just released a youtube app, so here's hoping.
