In response to this lovely fan art for M2 from Twitter user Tracker, M2 replied with the following statement: "Thank you for the great art, and your continued support! While we have concluded the Sega Ages series with Herzog Zwei, we are expecting further collaboration between M2 and Sega. Please stay tuned, and we wish you AGES of fun!"
In case that it wasn't clear that M2 isn't coming back with that very coy statement from Sega, the studio's Twitter account may have spilled the beans. I'll take what I can get!
