One extra year of development = 4 years for the next entry development
The games are normally on a ~3 year development. Unity was openly stated to have been under way 3 years before it launched.
4 years is great.
If you believe the dev diaries, Unity was in development for 5 years. Unity's problem was that it tried a lot of techincal things, and couldn't perform. Not to mention the actual game underneath all that wasn't even enjoyable.
Syndicate, while techincally competant and even if it got another year in the cooker, it would have still turned out to be "just another AC game"
What I hope these rumours are pointing up to is that AC 2017 is a serious shake up of what AC is. They can't keep using the same formula anymore.
So huh, the AC chronicles dont count ?
Also W_D 2 is this year no?
Would you consider Links Crossbow training a full Zelda game? And besides, those chronicles games are fucking trash.
