Madman Entertainment are releasing Transformers Armada DVD in the future, with season 1 around December 2013 I expect. Based on the upcoming covert art:

I expect Madman Entertainment have a similar deal to Shout Factory, and will release Transformers Energon and Transformers Cybertron on DVD in the future too.
