Yesterday, Comics Continuum reported that season two of Wolverine and the X-Men is "very unlikely". Further proof came when NickToons did not include the show in a presentation at MIPTV.
Today, Marvel Animation Age confirms that Wolverine and the X-Men will not be returning for a second season for reasons still unknown.
Wolverine and the X-Men season two has been in production, although there have been some delays. It is unknown whether the delays are because the show was not renewed or if the show was canceled due to the delays. Hopefully we will get an official statement soon.
In other news, Marvel Animation Age asked Spectacular Spider-Man producer Greg Weisman what he thought of the announcement of the Ultimate Spider-Man animated series:
I've heard nothing directly from Marvel, but I think the Ultimate Spider-Man announcement makes it fairly clear that The Spectacular Spider-Man is over.
The article also states that both Marvel and Sony have no plans to pursue a revival of Spectacular Spider-Man at this time.
