The Chinese description says "based on the highest acclaimed Yakuza 2, newly added playable Majima story". Although various sources (neogaf, Twitter, gaming sites) have passed the leak on, no one seems to realize (or react) to the new Majima bits???? (Wario64 ran the text through Google translate, which promptly converted Majima's name to "island") So consider this a scoop I guess?

Personally I am very glad more Majima is added. 0 was my first game (watched beast in the east, and now playing the Chinese version myself). Majima was so good in it that frankly I don't have much interest in Kiwami, and even 6, knowing he is not heavily featured.

Descriptions also mention using Yakuza 6's dragon engine, which has people excited as well. (Everything else in the text was fluff, new cast face scan, voice, etc)

Yakuza Studios is hold a live stream 8/26/17 at 6EST (here). Apparently there will be other surprises. (Localization? HD collection? PC version? new game?)

Edit: Updated trailer here. Makoto is in it!!
