They gonna keep shooting themselves in the foot? FFS, get your act together, Apple, and don't release a product until it's ready, and furthermore don't deny a competitor a fair advantage because you messed up. This is why I despise the closed garden system...
Come into the real world for a moment.
You're reacting to rumors that Google may have already submitted a Maps app to the App Store. And you are assuming Apple might delay for no reason. Do you know if Apple had a chance to renew its deal with Google on maps or not or under what terms? No, you don't.
Do you think Google Maps are perfect? NO. They certainly are NOT. Even after years and years and years they SUCK. They had problems in Southern California but they're absolutely unreliable in the Atlanta metro area. I always, always, always double-check with Bing and at least one other service. Does anyone complain? Would you know if they did? I submit corrections to Google for what little good it'll do. I also participate in the OpenStreetMap project.
This is Apple's first role out of Maps ever. You cannot expect perfection.
