Anyone still trusting anything Ubisoft does is literally not paying attention.
Hearing it's open-world should make you more concerned, considering the publisher; not less.
The company does not change, and only makes one kind of AAA game, just given varying coats of paint. Assassin's Creed is Watch Dogs is Far Cry at this point.
It's going to basically just be whatever modern-age AC was going to look like if they'd ever completed the Desmond storyline and got to current era more - bloat and a big-ass map covered in markers and 'activities', but really only like 5 fun things to do and a gameplay loop that'll get boring exactly five minutes after the Steam gameplay-based return window closes.
They'll spend all that time and money and it'll still be a worse espionage game than the jumbled, unfinished mess Kojima left on Konami's desk before fleeing the building 6 years ago
