Unless a corporate raider comes in and tries a management putsch by saying 'Ubisoft's executive team has destroyed shareholder value with their poor management of Ubisoft's valuable IP portfolio and failure to develop new IPs' then the margins and profits posted over the past few years will make Yves Guillemot and co argument for them.
We're at the inflection point I think for this game series, consumer backlash tends to lag in this industry with disappointing titles not suffering too much immediately from their lack of quality rather the opprobrium falls on the next game in the series 'Oh last years was boring I won't bother this year'. They haven't yet shown anything gameplay wise that makes me think 'Ooooo that's new' instead relying on a new traversal gimmick, where is the attempt to sell me on the story or promising some kind of narrative pay off for any of the no doubt hundreds of side missions? Watch Dogs was the last straw for Ubisofts brand of open world sprawl for me, none of the collect N objects, kill Y dudes, follow Z persons quests offered bugger all.
Back OT: Engine folks is it possible that this engine has a 'baked in' presumption of CPU power that was simply set too high as even with the apparent IQ tweaks we're not seeing much performance improvement here. In other words if an engine was designed for say a per cpu core 'power' of 100 and the shipping console is at 80 are there design choices that would mean that the engine could never scale down?
