Is season 3 the last season for Monogatari?

The last time I watched this series was about 2 years ago when it wasn't finished, but now I've watched all the way to the beginning of Koyomimonogatari and based on this timeline: http://bakemonogatari.wikia.com/wiki/Monogatari_Series_Timeline it seems like it is done. Someone please tell me its gonna keep going I need more of this wonderful show.
