I hope the price will come down!! They're really expensive!
Maybe Paul N can answer this but can we expect to see them at a similar price as the N channel part when on full release via normal distributors?

price usually drops when yields go up. i think they have been struggling with the yields for a while.

Ok. Made the purchase and dual 5U chassis plus boards. Talk about making a commitment! Thanks Zen for pointing in the right direction. Looks like people love your Pumpkin with the F4. Might be next on the list. We'll see.
