This gets back to the edit I made to the first post you replied to. I'll quote that here. 

I'm not saying you're necessarily wrong, by the way. Here's the central question: is it better to play it safe and milk something like Tekken, knowing it will be a dead property in 5-10 years? Or is it better to risk alienating the remaining core fans in attempt to revitalize a dying genre? There isn't a correct answer to that one until we're 10 years down the road and can look back and see. 

This central question can be applied to practically anything on Wii, by the way. Which is better, to stay with the safe shooters/fighters/RPG/action games that these companies have been churning out for decades now, with the same type of controller and gameplay style, or take a risk with something new on the Wii? Again, I'm not sure there is a right answer here. While the Wii is riskier, it's clear that the rewards are higher, as Nintendo continues to embarass the rest of the industry by making more profit than everyone combined, thrice over. But you don't necessarily achieve what Nintendo does; you can fall flat on your face instead.  By contrast, the older, more traditional styles of games have seen profits shrink and shrink for years now (this isn't just true of fighting games, but especially so there), but at the same time, these smaller profits are safe. You can depend on them. Companies know how to make these games good, and they can expect to reap the rewards of it. 

Take your pick.

Actually, you should reread. I certainly do. That's part of being a knowledgable poster. That's why the edit button is there, after all.

To your main point, obviously both are true. But if you're suggesting that Fighting Games are dying simply because it's stopped recieving support, that's foolish. The games that made the genre huge are all still around; Street Fighter, Tekken, Virtua Fighter, Guilty Gear, Soul Calibur, Mortal Kombat, King of Fighters. All still in production, with high production values.

Clearly, the interest in this genre has declined. Dramatically, at that. In this particular instance, pinning the decline of the genre on decreased publisher support doesn't make sense when practically every major series in the genre's history is still seeing new iterations.

I'm not even sure I understand what we're arguing about here. We do agree that traditional fighting games are a dying genre, yes? They've been in decline for a decade now, and that decline has been consistent and dramatic, with every major series in the entire genre going slowly but surely downhill during that time frame, with most selling 1/4 what they did in the early to mid 90s. Is this something you're seriously contesting? People don't like this sorts of games as much anymore.
