Rumor has it that Apple is going with an in-house (3D) map application… which, if accurate / true essentially means that Google Maps will no longer be used…
While they’ll in all probability be a lot of speculation (putting it mildly) perhaps this is a shot across the bow (i.e., a way to get back at the firm’s reported and since broken promise to not enter the Smartphone space?)
