Will it be left hand compatible?

Edit: Nevermind. Looks like it will judging from this picture. http://data9.blog.de/media/728/78007...5f26a07_o.jpeg

If its 30% faster than the 4pksr, would it still not be "far" from as fast as the current M12?

It is Fasst if you use a Fasst receiver with it. The one it comes with is the R304SB which is a type T-FHHS telemetry receiver but this radio can be set model by model to modulate in all types of Futaba's technologies including Fasst, S-FHHS and T-FHHS.

That means your collection of Fasst receivers will still work with the 4PX.

Well I'm sold. I hope this is out before the Snowbirds

More on the 4PX:

Presenting the New Futaba 4PX radio!

• The design of 4PX is completely changed from 4PK series
• Low steering position contribute to low center of gravity
• The weight is 15g lighter than 4PKSR
• An aluminum frame is inserted in the body to strengthen the structure
• All in one transmitter antenna (The angle can be changed)
• Transmitter weight: 555 g without batteries / 562 g with alkaline
• The response of T-FHSS system in 4PX is optimized and 30% faster than 4PKSR.
• Telemetry features can be used without delay in the response.
• 2.4GHz system - T-FHSS, S-FHSS & FASST-C2
• Following receivers can be used with 4PX: R304SB, R304SB-E, R614FS, R614FF-E, R2104GF, R204GF-E & R203GF
• QVGA3.5 inch TFT color LCD. The good quality LCD bring perfect visibility under sunshine.

• More crisp feeling at high-point on the detectable throttle trigger. A driver recognized a high-point by touch
• Throttle trigger is movable with a 7 mm range (Same as 4PKSR, 4PLS)
• Throttle trigger shape is optimized as well as stiffness is increased
• Combination steering rubber
• Steering angle can be selected from 32 degree and 43 degree are selectable on each side (Same as 4PKSR)
• A driver can find the best directivity by the all in one antenna
• A switch can be touched by a driver body is equipped on the bottom of the transmitter edge
• A LED which shows telemetry “Disabled” is equipped (This function is intended to a race which prohibit the telemetry function)
• Two different types of throttle triggers are included (Can be easily changed by a screw)

Sweet.

That's a bummer that none of my current FASST receivers will work, but at least the FHSS receivers are inexpensive.

I want one!
