Last we saw Yoda, chronologically of course, he died on Dagobah in “Return of the Jedi,” but since he is the badass to end all badasses in the Star Wars saga, do you really think that was the last we'd hear from him? Especially with these Disney reboots banking on nostalgia, Yoda had to conceivably make some sort of appearance in the latest saga? Frank Oz now seems to be hinting, probably under embargo, that our assumptions have been proven correct and we will see his creation appearing again on-screen next December:
“I feel like I’m a prisoner at war here, and I can only give you my name, rank and serial number. To be true to the people who asked me, and they are kind of my family, I have to say I’ve been asked not to talk about it. I love Yoda. I would be happy to talk to you about it at the time they let me” - Frank Oz

Snyder has mentioned in the past how “Sucker Punch “never really got finished correctly,” and that it was “not really the correct cut.” The extra footage is actually already shot.
