Tubes 2 application?

[Manj27]

Does anyone know when an application called "Tubes 2" will be released for the iphone? The developer has listed "coming soon" on their site (http://www.visualit.co.uk/Apple/iphone.htm) for the past month with no updates to availability.
It looks good from what I can see, and will definetly be a helpful app for my journeys on the underground. Don't think other developers have listed any tube apps for the iphone as yet.

I was just thinking about this, I was comparing my apps yesterday, the ones still missing on the iPhone coming from a Treo, and this was one app I'm missing. There is a great subway map at the app store, but the way this app calculates where to transfer and show you the direction in a moving graphic is pretty cool.
