Google would've always made sure Andriod had a competitive advantage in Maps, one of the most important functions/apps of a device that's carried around by its user, and Apple is keen to cut their reliance on Google, their biggest competitive threat, out of iOS as much as is practical. While Google Search isn't going away anytime soon in iOS, Siri makes some strides even on that end.
Apple waited for their own Maps implementation to introduce some much needed enhancements, and using their own set up for the data gives them better flexibility for adding them. My fear, as an iPhone user, is the same as has been mentioned: the search function and location information in the new Maps is not likely to be nearly as powerful nor refined as Google's. I've already been using MapQuest4Mobile on iPhone for voice guided navigation, but I often have to use Google Maps to find a particular address before feeding it into MapQuest4Mobile for the actual navigation.
Street View will also be missed.
The pressure from the increased competition should push all maps apps to finally improve a lot, though.
