Assuming Jules has a branch. While it makes the most sense for the three branches to be Logan, Sam and Jules, I get the distinct impression that L&P has no real interest in the lesbian paths of the game. If you look at what was introduced at the start of the game with Jules' strange behaviour, not being allowed to wear bikinis, Sophia being invited to Jules' performance of MSND compared to now - where L&P is quoted as saying that there's nothing sinister behind Neil's behaviour. And while we're still waiting for Jules' performance, Sam has decides to put on a concert, and has it the next day.
Then there's L&P putting it as subtly as a brick to the face that under no circumstances will Ellie give up men, no matter how much more enjoyable it is with just Jules and Sophia. Or that the woman that starts off the Lesbian Temptation - Alyssa, is now firmly in the Dylan route and only so that Sophia will eventually get dicked on his route.
And the niggling coincidence that the bonus storyline might finish on the same day that the Ellie branches begin. It's entirely possible that L&P might drop the Jules branch that might have been planned and kick her while she's down and instead go for a Dylan/Ellie branch. Wouldn't be the first time the story has been changed for Dylan fans, and wont be the last.
