I think we are now at a stage where the promotion and marketing for Shenmue 3 will now take the path that more conventional games do so. Last year, Deep silver had just come on board as Gamescom was taking place. When last years event was announced via the Kickstarter page, it was done through Awesome Japan under the advice of YSNET themselves. Now its a year later, with Deep Silver handling all public appearances, promotion and marketing, I wasn't expecting any announcement like the one we seen last year.
If there was an announcement to the public, that would mean something is planned to take place with the public, ie. a meet and greet like last year. That wasn't even part of the plan last year, and had to be put together last minute due to the amount of people who immediately bought accommodation and flights to Germany.
When YSNET go to these events, it will solely consist of business meetings and journalist interviews. That's it. That's just the way it works. If YSNET are going to Gamescom this year, it will be for behind closed doors meetings only, so there's no need to announce it to the general public at all. If they do go, then the chances of seeing something online are increased. Journalists and things will be shown new footage in their meeting, so that usually gets released to the general public.
But, since there hasn't been no public confirmation YSNET will be attending Gamescom at this point, we all have no choice but to wait.
