There's something rotten going on at Ubisoft. The Watch_Dogs debacle is just too suspicious. Why would the developers intentionally gimp their creation. Wouldn't they want it to be the best it could be?
If I was to guess I would say it's a decision being made on a corporate level. Possibly by a company that has partnered with Ubisoft on these titles and doesn't want the world to know that its new console is already underpowered.
