And Luke is apparently the "last Jedi" 30+ years after RotJ.

Exactly what have our heroes been doing since defeating the Emperor and Vader anyway?

Luke must have been sitting out sulking somewhere by his lonesome all this time. The Rebels still can't manage to stamp out the Empire.

There better be some good explanations for all this, but I suspect I won't see them.

Isn't "Jedi" a plural as well as a singular?

(Edit: I googled it and most people seem to agree that it's "Jedi", not "Jedis" when talking about more than one Jedi knight.)
