User blog comment:Mobo85/"Phineas and Ferb: Mission Marvel" Debuts August 16/@comment-1896159-20130628214646

With the recent announcement that Good Luck Charlie would end after 4 seasons, I've admittedly been worried about this show, seeing that it's now also in its 4th season. But from all indications - including a little bit in another blog saying Dan & Swampy were already pondering a 2nd Marvel special - this show isn't going to end anytime soon. Seems like the show is only starting to hit it stride, and with the list of episodes already revealed for this season (and no doubt still some still kept in secret) I think we're in for a treat when the show inevitably gets renewed for Season 5.
