I still don't get why these threads pop up every day. Jedi Luke is the ultimate character in the game, and will be released very late when the game is near its end, or they have nothing else to do. They are saving him for something extremely special, not releasing it in a few weeks, when there are a lot of other options. Same goes to Jango or whatever, they aren't gonna release all of the iconic characters so close together.
Also, I also don't understand the notion that Episode 8 Luke will be released for the most part, instead of Episode 5 or 6. We have no idea what he will do in Episode 8, so he might be crucial. However, literally 99.9% of fans prefer the OT and OT Luke to the new trilogy and a potential Episode 8 Luke. The most iconic character in all of Star Wars is not gonna be left out of the game, and we aren't gonna have 3 different Lukes. If they want to emphasize the new trilogy, then they will make more Rey's or Snoke or whatever, not old characters.
And a cool idea I think could be used to unlock him, when he comes out. You would need 7* Raid Han, 7* GK, 7* Yoda, 7* Palpatine, and 7* whoever comes out like those (5* unlock through raids/events).
