Exactly my point. Due to what that combat did for Batman and the subsequent games that copied/adopted it, a KotOR 3 could very well jump on that bandwagon, making the game 100% about combat. Besides, KotOR is not in need of any assistance like Batman was 
It's hard to know what BioWare will do in terms of combat. KotOR 1/2's combat is pretty antiquated by today's standards. I can't see KotOR 3 being a full on action game either, but the combat might be more action-oriented than DAI. I could see BioWare perhaps using TW3's combat system as a model to perhaps go from there. We'd just have to wait and see.
And i also think that Disney will "milk" the Star Wars franchise to the limit.
That is inevitable. A new movie every single year and EA making Star Wars games around the clock? All Disney wants to do is milk Star Wars until there is no magic left.
What, no! What makes you think that would ever happen???? 
EA has hinted that Bioware (as well as other studios) https://www.trueachi...s-star-wars.htm are in someway working on their avalanche of future star wars titles. Could this mean KOTOR 3 or some kind of a spiritual successor. Maybe? Knowing EA and how different Bioware is from what it was in 2003 this would probably something more...action oriented. Just look at the chart from their financial outlook conference this year. http://www.dualshock...n-action-genre/
It's worth noting that "action game" is probably referring to BioWare's new IP that BioWare Edmonton is working on and not a Star Wars game. While it's possible the Star Wars game BioWare seems to be secretly working on in their BioWare Austin office could be action-oriented, I'm still under the impression it will be an RPG.
If so then I hope they stick to the original ideas for it if possible.
What do you mean exactly? Gameplay mechanics? Story? I could see them trying to remain as faithful to the original two as possible, but without a doubt they'll modernize the game accordingly.
