Earlier this afternoon artist Christopher Franchi shares a brief teaser picture for American Pinball's next game. The retro-futuristic shot states that the Company will have a March reveal for its next machine, which is rumored to be the trademarked title Galactic Tank Force.
American Pinball (AP) is listed as an official vendor on the website for the upcoming Texas Pinball Festival (Frisco, TX 3/24 - 3/26). Furthermore, the just released schedule for the event shows that AP is doing a presentation at the event on Friday 3/24 at 5:00 PM. There's a very good chance that AP's next pin will be unveiled then.
UPDATE: I'm hearing that the first production sample of Galactic Tank Force is ready and playable. It's difficult to say how long it will take for AP to begin producing the machine in significant numbers.
