I found more of the synopsis for Kung Fu Panda3 and I found some exciting stuff. I'll list things for people who don't feel like reading the whole thing nukethefridge.com/2015/04/23/o… .
1. It's seems like the panda dad is coming to Po (darn I was hoping Po would find him. I guess it's the better though so Mr. Ping has a reason to leave.)
2. Oogway might appear again since it seems that his voice actor is listed.
3. The villain seems to be named Kai (I did some research and it means "victor" or "open" there's more but I don't think it's meanings for baby names)
4. It seems like Po's brethen are going to be just as clusmy as Po probably.
Here's another pic as well mu-laohu.tumblr.com/post/11720… .
Here's to hoping for a trailer soon! Thank you for reading and may God bless you all
