The TomTom app was eagerly sought out last year, but of late has fallen a bit behind market leader Navigon. This new release, with real-time info and Google local, will give both apps rough feature parity.
The current TomTom app is on sale for U.S. $49.99 at the app store (U.S. maps only) and it includes a "free update to the new version as soon as its available." That would indicate that some or all of the new features will be an extra charge for current owners.
Version 1.3 will be available as soon as it passes through the App Store vetting process.
