Hopefully not too many. After all, the devs said they wanted to avoid the "jedi assualt squads" from K1. I'm thinking Kreia is the only Jedi you get, and people like Handmaiden, blondie, and Vis you have too train.
I doubt people like Atton or Mira become Jedi. I hope not, anyways.
It kinda ruins it if EVERYONE is a freaking Jedi. I was hoping it would be Kreia and one apprentice per LS/DS path and thats it.
