Future content question

I realize there may not be an answer but I want to ask as I am now fully addicted. I haven't even played my collectors Dark Souls 3 because I've been loving this so much. Anyway, I was researching a trailer for this and it said "6 content updates"... I've been playing for two weeks, so i know TG is one of them. Orsinium also? Are they only planning six major dlc updates? Or are they going to support the game for many years to come?
