real time mostly, something like dragons dogma.
or RTWP in the Dragon Age 2 / Inquisition sense.

When Sven talks about attakcs not missing, i cannot imagine turn based (OS1 and 2 got accuracy stats) or RTWP (all RTWP games i know have misses)
So i imagine a combat system where you directly controll one characters and whack people with attacks, thats the only system in which i can see not hitting someone beeing "Not fun".
Which makes me think that the combat will be action based, with maybe some party stuff like a "tactical view" where you can give commands.
