And really to be fair, it tooks years for Google to provide its current iteration of their maps. Do we all remember when it first came to market? Yahoo and MapQuest had better offerings.
As I said there is no real incentive for Google to provide their maps as an app. Their licensing agreement was over, now unless you are an insider was it Apple that wanted to sever the idea of having Googles maps packaged into iOS? Or did Google want to end their relationship on that front?
Maps will no doubt get better with the type of resources Apple can afford, but it will take months for it to become a viable option to Google Maps.
