It certainly will be better but I'm not holding my breath about Apple maps surpassing Google Maps any time soon. Google bought a Rasmussen brothers' company (what eventually became Google Maps) in 2004. That's eight years of product development, data collection, storage and refining -- all at Google's pace. Will Apple find some shortcut to compress this time in one-two year? Unlikely.
It's very easy to underestimate the amount of pure, repetitive effort required to build products of this sort and how hard it is to "disrupt" the industries with players like Google.
