At this point I feel like they are not doing one....Are they actually doing one?
With TGS being a week earlier I would have expected it to be announced earlier, though I guess it doesn't matter as long as press are invited early enough.
Last year they announced it at like August 22nd or something... at last year's TGS was later than this year, so if Sony was doing their usual conference it should have been announced by now...
And if Sony was doing a conference, I feel like Yakuza team would have waited and unveiled Shin Yakuza at TGS instead of their own even this week..
