Yasuke is actually a fantastic choice as far as history/narrative goes.
A shame the game looks like more generic Assassin's Creed Mapfucking+Crowd Supermurder.
Which is fine if that's your thing, but I haven't been thrilled by an AC game since... well, AC1.
The Story of Black Flag was tongue in cheek 100% and very blunt about it... yes.. but gameplay wise, Black Flag was definitely the requiem on everything the series had to offer (and more).
And again, you are right. I stopped caring. I wouldn't even know a new AC is coming if it wasn't for all the stupid stuff like "I don't want to play a black man or a Asian woman" or "why is the first playable Asian protagonist black"... the game itself well... why?
But should Ubisoft go down, I would miss their quirky games like Splinter Cell, XIII and even Far Cry...
even there they left no quirk. they found the ac formula to work extremely well and made all their other games into ac-spliced gray sludge. some even before. they removed the best part of rainbow six. splinter cell became unrecognizable. ghost recon became open world or some shit.
apart from ac, thanks to the historical settings, I can't tell any of their games from another. all their games have the same gameplay loop. all their games have drones. all their games have towers. even their fucking racing game had towers to unlock map areas ffs. they're just a parody of themselves. in AC4 that was literally the case.
