They'll do what they did for D:OS2, of course. What else would they do?
There will be a soft level cap per act, after which your XP gain will slow dramatically - so it will be quick and easy to get to the level cap for the act no matter how you play through it, but it will still be possible to get to the next level or two if you really scrape hard for XP - however, doing so won't help you MUCH, since there will be a similar soft cap in the next act.
They really did that? That's garbage.
It's manipulating the player. No matter what you do, you will still be exactly the level they want you to be when they want it. So why create the illusion of linear experience points in the first place? They might as well scrap the concept of XP altogether and just give you a full level-up whenever they think it's "time". The end result would be the same without the unnecessary charade of accumulating XP.
Why punish a player who is being thorough by soft capping their XP? They could just add a creature or two to an encounter if the party is over-leveled. But I guess Larian want to reinvent the wheel and turn it into a square wherever possible.
