Remembered today that in Rebels: The Siege of Lothal (s2 eps 1 & 2, if anyone wants to check it out - do) Vader suggests to the Emperor that Ahsoka could possibly lead him to Obi-Wan. Palpatine responds with “Perhaps… IF he lives.”

Rebels is too serious a piece of Star Wars content to be retconned. The writers need to tread carefully. Besides, the show is sounding like an adventure Obi-Wan has off-world, and I can’t see him risking everything - literally everything - to seek out other Jedi or something like that. And of course Vader and the Empire can’t know where he’s hiding, he wouldn’t risk them finding out either.

There are loads of lines from A New Hope that clearly suggest Obi-Wan has not appeared for 19 years: “I was but the learner” being one, other instances like Tarkin being sure Obi-Wan has died at some point during or after the Jedi purge. I’m still concerned about how this show will impact Obi-Wan’s overall story and even the story of Star Wars as a whole.
