Daniel Ingram tossed this up on his Facebook page yesterday.
I know every day we are checking the box looking for some kind of season 3 news that isn't community edited and a total guess. It's only a matter of time!
A lot of you pointed out the plural "Seasons" in Daniels message up there. I don't think there is any doubt that there will be more after season 3 of pony, and I'm pretty sure he is just hinting at seasons of the various shows hes working on showing up this fall. Everyone keeps pointing it out though, so have a mention!
Onward to hopefully an announcement about some new pony soon!
