Prop II Quadrature Counters...

Has there been any hint of what we can expect in terms of performance yet such as maximum count frequency? Any built-in filtering of noise, etc?
I need to handle several servo-motors @6000 RPM with 4096 line encoders (=1,638,400 counts/sec).
Trying to decide whether I should wait for Prop II or go ahead and hook-up dedicated quad decoder/counter chips to the current Prop. I'd prefer to count directly on the prop because I have a few other ideas about handling the various encoder signals etc.
Do I also understand that each pin can be configured as a bipolar DAC and would this have +/- 16bits resolution?

Counter info is sadly very sparse...
So you should use a dedicated chip and available Prop, and it will be easy to remove later.
Something like the LS7366R, is small, and lets you move onto more complex stuff quickly.
I'd wait for the P2 too.
