I'll be deliberately short on details, but I'll say prices will go up soon, in particular for the D09, just verify the current price at your distributor. For the D09D14 only Farnell is still quoting the previously going rate ($0.38), Digikey put up almost $8 each in a 6000 tape.
We are in a phase of pure speculation.
I know many here have started on the D09, make sure to review your project, select another mcu if you can, the magic is set to evaporate.
My collegues know Microchip by their fame, and they seem keen on living up to it.
Time to jump ship if you can.
