I've been trying out a Pi 2.
I have pigpio working after a fashion. There is still an unknown amount of work to be done to get it running as reliably as it does on the earlier models. More than a couple of constants need to be changed.
One good thing about the Pi 2 is that piscope appears to be usable on the Pi itself. Personally I always run piscope on a laptop networked to a Pi (running pigpio).
webm of piscope/pigpio running on a Pi 2 (fixed PWM on gpio 7, 8, 9, 10, and 11, ramping PWM on gpio 4).
