I don't know if anyone has posted this as I've just returned from a long hiatus but the G1 Series is being released on DVD again. This time in a Decepticon themed set. It comes with an exclusive comic from Simon Furman and is $40 cheaper than the original release.

Release date is listed as 24th June
