Two conventions in NZ (Christchurch and Wellington) of similar style to Supanova here, has the TFs voice actor Michael McConnohie scheduled to be in attendance at both shows.

Christchurch is next weekend (27/28 March) and Wellington is the weekend after (2-4 April), for anyone here who is close enough to make it.

He worked on the RiD series, but is best known for his voice roles of Tracks and Cosmos in the original Gen1 cartoon.
