I saw at the bottom of the Episode List article two video previews; one from Fall 2012 (when the anime started) and another one for WInter 2013. What does that mean? Will be there more Sakurasou for this winter?
If you haven't aware, Winter is happened between January through March, which means, in Northen Hemisphere countries, a year started with Winter season.
So it's just logical that the preview stated Fall 2012 then Winter 2013, which the first preview is for first part of Sakurasou which aired on Fall and the second preview is for the second part which aired on Winter.
