Anyone who enjoyed the later entries into the JK series should not even be looking forward to FU in a similar respect. You have to understand that Jedi Outcast and Jedi Academy were both made by a largely Quake-style developer that Raven Software was at the time. That is why the multiplayer was so perfect. In fact, the games were built off the Q3 engine.
FU on the other hand, will be a console romp. It will probably be good, but I don't expect anything near the longevity that the previous series gave.
