Wasn't there supposed to be another Iron Man series at some point - to replace Iron Man: Armored Adventures?
Not that I know of. Apparently there's still talk about a possible third season for IMAA.
I haven't been holding my breath. :P They would have announced something by now, and as much as I liked the show, they came to a fairly satisfying conclusion that I can live with, both story and character-wise. I'd love to see more with solo shellhead and a more mature Tony. The 90s Iron Man cartoon was dreadful IMO but I'd think they'd give a solo show to Marvel's most popular movie character and not their least (at least until Avengers IMO, but I digress).
