According to Cosmic Book News, Lucasfilm might be developing a Star Wars spin-off movie set between Episodes III and IV featuring Darth Maul, Obi-Wan Kenobi, and a 5-year old Luke Skywalker on Tatooine.
I doubt this is the case mainly because Disney really seems to be shying way from anything in the prequel era.

– Set between Star Wars Episode III and Episode IV.
– Said to feature Ewan McGregor reprising the role of Obi-Wan Kenobi in his exile on Tatooine.
– The villain? Darth Maul hunting down his nemesis with a possible plot point involving a 5-year-old Luke Skywalker somehow tied into the story possibly as bait for Obi-Wan.
