Any R4 Details?

[Keith Pleas]

Does anyone have more information on this R4 update? It appears that v.17 of the MFD software from May is R4 ready, but the Evo and sensor and P70s have to be updated. But the "Download Now" takes you to the v.17 download page. I can probably get the files I need, but I'm looking for some details on:

- 9-axis gyro stabilization of wind and navigation data
- Increased accuracy and responsiveness
- Evolution TrackIQâ„¢ for tighter track-keeping and acquisition
- Improved interface and calibration

There's also the note "Enhanced integration with popular Autopilot Joystick Controller and solenoid drive systems." What joystick controller is this talking about? I'd LOVE to get a STNG joystick - is there such a thing coming?
