Not sure what I think about this.
MASK is coming from Shout! Factory. That is confirmed.
Beast Wars is coming from Shout! Factory on June 7.
Transformers - The Complete Series is set for May 24, but I can't figure out what this set it. I'm guessing that Shout! Factory doesn't have the rights to the show and Vivendi is putting out the inexpensive complete set.
I've not heard anything about the GI Joe DIC stuff. Wouldn't be surprised if it did happen.
