Yeah... About that.... I don't think it's going to happen as much as I may wish otherwise.
I enjoyed the Inquisitor story, the Jedi knight story (consular was meh...), and from what I saw of the imperial agent it seemed like it was also a good story.
I mean, if they really wanted to, I guess they can make a KOTOR 3 or something, but it just seems to me that killing the franchise is the likely thing to do for EA.
It doesn't have to be in the Star Wars universe, I'm just a sucker for espionage stories =P
The IA one was well done but as you mentioned before, all the other stuff gets in the way. I get a few cool missions dealing with my IA stuff and then it's "Sorry, do the entire planet to level up enough to be able to do the next mission".
My guess is also that KotoR as a franchise will be dead after ToR is done. I seem to recall EA mentioning something about BioWare working on a Star Wars game when they got the licence to make them from Disney, although I'm not sure if that was referencing continuing work on ToR or something else.
Even if it is something else however, I'd imagine it will try to link up with the new movies as they come up and will probably be from that time period. Especially considering that Disney has ruled the entire Old Republic era that BioWare created to be non canon.
