Argon added it's Tokyo bikes to its website:

The geometry has been updated a bit, going longer and taller. And Argon claims there is a difference in the Sprint/Pursuit frames, but given the geometry and details, I have a very hard time believing they are really making two different frames. But I do know the forks are different on each.
Also interesting, it only accepts Thru-Axle front wheels. I'm not actually familiar with any TA track wheels.
