It has been described as hybrid of both by devs I believe. You can have both real time battle and pause for tactical mode.
DAII combat was the same design. Both DAO and DAII were already real time with pause. The main difference being that DAII was faster paced (honestly I used puase more often in DAII due to the faster pace) and the significantly less useable camera. Obviously, all abilities/classes have been rebalanced for each game so those are technically different; however, the games play the same way. Inquisition appears to have DAO's camera with a pace more similar to DAII...which are minor differences.
Also, I nearly forgot about people who played DAII on console and had that wretched lack of auto attack and had to button spam.
