Stunning discovery, right? Take this report with a huge grain of salt not because it's doubtful but because anyone could have guessed that. According to the latest rumors Yoda and some other deceased Jedi will make an appearance in Episode 7 in force ghost form...
So according to a cosmic booknews' source:
Star Wars: Episode VII will feature Force Ghost Yoda.
We're told that Yoda will have words with Luke Skywalker about a rising unbalance in the force and the need to preserve the Jedi.
There is also talk amongst production that would give a nod to the previous Jedi characters in the form of holographic pictures in the new Jedi Temple.
It's said it wouldn't be anything major, but would be in a background sequence featuring holograms of Yoda, Alec McGuiness as Obi-Wan Kenobi, Liam Neeson as Qui-Gon Jinn, Samuel L. Jackson as Mace Windu as well as others.
I don't know about you but I think someone's going for the clicks with this. :)
