Not sure how much I care about Google Street view with the advent of iOS 6. For me, I guess it's still a wait and see. Even if Maps in iOS 6 are horrific, I currently rely mostly on Navigon, so the impact will be minimal for me. I am rooting for turn-by-turn to be excellent, as a fall-back option for me and I think it will be a killer feature for all users -- many of whom don't have Navigon.
