Eventually reviews will get worse, sales will fall, and spinoffs will get cancelled. Then there will be a year with no new AC game. And a year or two later it'll get rebooted. Hopefully all the bad design decisions will be gone, and something more solid will emerge. It still has a lot of good qualities. They just need to focus on what is working and not be afraid to trash the rest. Sadly, that won't happen until an AC game flops hard.
