Who cares what gender Revan is. As long as there is something/someone from KotOR in ep. 7, I will be very excited!

Well, KOTOR takes place several thousand years in the past, so unless you're talking Force Ghosts, I don't think anyone will be making appearances 
Well, so the "Force" awakens ... both light and dark are gone or asleep, as the title suggests ....Sith are all gone, Jedi are all but gone (Luke, maybe Leia).
So the perfect opportunity for characters of all sides to search and learn about the past of the "Force", force-spirits, datacron-holograms, relics, that kind of stuff. A mere mention of "Revan" in a conversation would be enough to make fans happy, and all others wouldn't care anyway...or a specific mask, apparition dressed like Revan etc...
Though I have my doubts for this to happen it would be cool...
And to those Netflix-series? Well..it might have possibilites but the thing with Star Wars is: It takes place in a galaxy far, far away, and not in the streets of New York (or wherever Daredevil & Co take place). That means "BUDGET!" - CGI works wonders, but if it looks drstically more cheap than the movies? Not sure ... But if they go that route: Keep the Jedi-Stuff to a minimum and concentrate on "normal" people like smugglers, bountyhunters, criminals, brave soldiers of the Empire fighting against terorist-scum etc (and as soon as the ratings fall you can still pull a "Worf on DS9/Seven o Nine on Voyager" and get some Jedi on board to make the kids craving lightsabers happy and stuff...)
