Last week the Sega release schedule outed a Yakuza 1 & 2 HD remake, and now the company is promising a major Yakuza announcement on their website.
The website doesn't say much, except that an announcement is coming tomorrow and it has to do with Yakuza.
It doesn't seem like the announcement has anything to do with the upcoming Yakuza 5, as it is mentioned on the main homepage and not on the separate Yakuza 5 website.
While Sega has yet to confirm or deny the Yakuza 1 & 2 HD remakes, it definitely seems plausible that the announcement will be concerned with this.
We will keep you updated when more news comes to light.
