I swear CN has produced anime in the past but most have been forgotten. The only one I can remember is IGPX (inline skating mechs) But I swear there where a few others I'm forgetting
Also in other news the Pluto anime might not be dead. Maruyama showed up in a video for a con in D.C. called Otakon last weekend were he mentioned an anime M2 was working on for 5 or 6 years would be due soon. although the key word is "might" because
A; he didn't specifically mention Pluto so it might be a different show,
B: the source is some twitterfag who apparently works with Otaku USA Magazine,
so unless the video actually surfaces take it with a grain of salt
Speaking of Pluto and on a sadder note, Fred Ladd, the guy who originally brought Astro Boy to the US passed away a few days ago, so that kinda sucks.
