I still think it would be a cool extra surprise if it was revealed in Sith that Obi-Wan was actually Luke's real father. Yeah, the OT is awesome and Darth/Luke still resonates, but it's almost like, in those movies, DARTH is Luke's father. The PT Anakin's character is such a whiny douchebag that it's a bummer to think he's Luke's dad. It would almost make more sense since Obi-Wan is 10x more noble of a character. Anakin could just *think* that he's the dad because he was with Padme, but Obi's unrequited love for Padme could've culminated in one night of bliss while Anakin was out doing bad Dark Side stuff. Or something. Crazy, I know, just some interesting speculation that I started thinking about when I saw ROTS.

With Obi-Wan and Padme having more chemistry than Padme and Anakin anyway, and if there was no OT, Obi as the pop would be neat. To me, anyway. Like, if only the audience, Obi-Wan, and Padme knew, but Anakin assumed it was his.

Evil thought: What if Obi-Wan is Anakin's father, and thus the reason why Obi-Wan felt the need to train him? What if all this time Obi-Wan is the one who pushed Anakin away (by being demanding, etc.) towards the Emperor, who treated Anakin more "kindly?" This would mean a younger Anakin in the prequels, tho... OR alternatively....(even more evil), Obi-Wan is Leia's father? Perhaps after Anakin had gone over to the darkside, Obi-Wan and Padme got together, and she later became pregnant, unbeknownst to Obi-Wan (they are somehow separated, or she dies before he finds out)? This would preserve an older Anakin and their friendship, but build in more surprise about Leia for ROTJ, another movie that needs tweaking.
