Alternate theory: Ed likes trolling Rain fansRain is in, despite these little haters. Did you notice how Ed never trolled about mileena being out?
Rain was constantly trolled by Ed Boon, if Rain is out, you can say that Ed doesnt give a shit for the fanbase of a big requested character.
I mean, Rain was tweeted so many times for Ed Boon, and most of the time giving us the feeling that he would not be inside.
If Rain is really not in, that was teased a lot of times for Ed Boon. But Mileena? he never said anything, and she was equally requested than Rain. Boom, she is out.
With this tweet i noticed that Ed Boon can be a troll, but he dont want to "hurt" people with their high requested, i mean, he doesnt tweeted a joke about mileena, that was most an apology. With Rain he overtrolled all of us, and i dont think that its because "Some people have once heard that he does not like the character".
