Out March 4th are two DVDs from Madman Entertainment...

30 years of Optimus Prime

30 years of Bumblebee

Each will have four episodes on them, and cost $15.
They will both have an episode from Gen1, Animated and TFPrime, while Optimus will have an Episode from the Unicron Trilogy (probably Armada).
(Bumblebee will probably have two episodes from Gen1, as there is mention of Goldbug in the description.)
