Good points. Subsim may have 65,000 members, but only a few hundred are actually active, and don't have a lot of influence on the gaming industry.
Here are some sales figures for the top-selling games.

Even the worst of the best-selling games topped one million units sold. Silent Hunter doesn't even rate 10% of that. Couple that with the idea that even if Ubisoft did make a new one there is no guarantee that it would even be as good as SH5, much less a lot better.
