Honestly, I'm not thinking its looking good. I'm sure Bioware knows there's a problem. I don't think EA cares though, and their likely to just say "More action, less development time" and run the franchise into the ground.
In either case, if things continue the way they have been, I'm not going to like it:
ME1: Brilliant.
DAO: Brilliant.
ME2: Great.
DA2: Poor
ME3: Bad
ME3+EC: Poor
What would win it for me, if done successfully, is a return to DA:O in most aspects, and with only 1 or 2 things in DA2 coming across to DA3.
I would like the DA:O style of Aesthetic.
I would like the DA:O style inventory back.
I would like the DA:O style spell combos back.
I would like the DA:O No Dialogue Wheel back.
I would like the DA2 ability to ask your companions on what they want to say.
I would like DA:A Anders back [If he's in the game].
I would like DA2 style writing for the characters for other characters.
I would like more DA:O styled combat, though moving at a slightly faster pace.
I would like the size and scale of DA:O back.
I would like the levelling and stats of DA:O back.
I would like items to stay largely away from "Generic Sword" and "Generic Sword with damaging enchantment" and instead be more "Item with enchantment that will help sometimes, and be unhelpful others".
I would like a large, nation spanning conflict to fight in.
I would like for previous choices to have some reasonable consequences [And no retcons].
That would, if reported to be true by the people who bought the game earlier on, earn the game my sale.
If its DA2 combat with the DA:O inventory and more areas than DA2, but less than DA:O with little else changed - I'm not going to like it.
