Nothing to report yet (June got busy!) but I have been doing some behind the scenes work.
The tiled, dragable map display logic used for the main map (and iframe) and the touch version were completely separate code. If you've played with the touch version you know it has some nicer features, such as intermediate zoom levels and using available images while others are loading so zooming in is a much more pleasant process. I've been working to unify the code between these, and it's almost done - I just need to get the overlay and the you are here features for the iframe API ported over and I can push the update.
As a side effect, this will allow devices supporting touch events (iOS, Android, etc) to interact with the main map page, although the interface will still be kludgy. That'll be the next thing to fix, followed by those data updates I was promising.
