according to Danny's interview and report panda and penquin are alive and kicking, bolt-on additions to the hummingbird just as they were with the previous core.
I certainly can't imagine google just abandoning these algo's. Supposedly Penguin cost a lot of money to implement and that's why they seldom run it. That was my understanding anyway.
