Thats no lens flare!
Not only is Anakin returning to Tatooine, but it looks like R2 is as well. And of course, because every single detail from the OT must be tied in and exploited, the Krayt dragon skeleton is there again. Maybe we'll find out that Anakin killed it :p (hey, thats not as unrealistic a possibility as it seems, given all this). Elsewhere there is a screenshot of Jabba the Hutt, apparently.
