Admittedly I do have mix feelings on Yakuza 6 as well, but I thought the decline began before 6. But yeah it will be interesting to see how Shin does.
Yeah Yakuza 6 was the first noticeable FW drop in Japan, at about 220k~ when Yakuza 0, 4 and 5 all sold about 330-360k FW
From what I remember the Chinese release made up for the poor FW in Japan. It could be Yakuza burnout but we won't know for a minute.
"I think it will be the HDS"-Me in regards to Nintendo's next handheld.
