Well the game Outcast didn't sell all that well--I doubt that would be too much of a problem.
They were already moving away from it by Jedi Knight: Mysteries of the Sith. Also, that expansion pack might be some of the cause for confusion? It was definitly a part of the DF series. So that would mean we should be up to DF 3.5 or 4 now. Rather than deal with that kind of confusion, just give the name from the more successful part of the series.
As for the Outcast part--I'm guessing this also relates to the situation that emerged with MotS. Kyle is clearly outside the normal stories in the extended universe. However, they are always trying to write him in and make things fit (afterall, the X-wing games are pretty much responsible for the highly popular X-Wing series of books) so there needs to be a reason Kyle isn't a part of the normal group of Jedi. Maybe he's gone back to his Bounty Hunter roots or he's on some sort of secret mission to find the remants of Empire. Some warlord or something who is getting a little out of control. By completing the task Kyle would have a chance to come back into the main fold and lose his outcast status.
