Isn't a surprise announcement no longer a surprise when you announce that you are going to make an announcement? Perhaps the surprise was that this Yakuza seems to be taking the series back in time, Way of the Samurai style, to the Meiji Restoration. In which case, though, isn't that a surprising announcement? Semantics, I suppose. Gangsters don't have time for that.
Given the terrible initial sales for Yakuza 1&2 HD and a seemingly tepid response towards recent franchise additions, I suppose it makes sense to slap on a new subtitle and swap the setting. Details are sparse, but we'll apparently learn more in an upcoming Famitsu.
Until then, have a good look at Ryoma Sakamoto. Check out that strong brow and chin stubble. What a handsome face he has. Looks good for smoochin'. I think I'll lay some smooches on my monitor right now.
