Quote from this link page on Hollywood reporter.com - Link see bold stuff for star vs news.

'Star vs. The Forces of Evil' returns for its third season in the summer; 'Milo Murphy's Law' is getting a second-season renewal.
Disney XD has ordered a second season of Milo Murphy's Law, starring Al Yankovic (aka "Weird Al").
In addition, the network has ordered a fourth season of Star vs. The Forces of Evil, starring Eden Sher (The Middle), ahead of its third-season premiere.

So season 3 sometime this summer and a fourth season to come after that....thoughts?
