obvious answer it's demographic.

but it believeable it woould have done better on the HD console not because graphics, but because it would have gotten more support.

If they make a new one obviously it needs to be a longer game, people think it should be an open world this time round, and they would need to make more ways to kill your opponent, people said no more heroes was a good game but it didnt appeal to me, im not saying it wasnt a good game but i got way more enjoyment out of Madworld

It's also believable that a Wii version of Bayonetta would've outsold the PS3 version.  Y'know, because MadWorld outsold it.  Demographics!

"(...) But we were thrilled when they tried to do a mature thing on Nintendo.”
I'm still puzzled why people think violence = mature.
M-rated , yes... but mature? This game was targeted for teens not for adults.

Hmm.. I think you are underestimating the work and the influence of publishers..

You know, game development takes years, so a dev needs to have lots of resources to finish a project (especially if it's a full retail game), but most don't have that kind of money, so they need hefty amounts of credits. Devs usually have month to years without any cash flow, so the conditions for credits they'd get (if they even get a credit) are atrocious and this is where publishers come in. They are bigger and have more constant cash flow, so they get better conditions for the credits (and probably the only publisher right now that can afford game production without credits is Nintendo) and can make sure the devs can finish their games.

Additionally they know the market and the products way better than any bank out there, so they can judge which projects are worthwhile or at least worth the try and which aren't.

This comment seems to signalize, that Sega wants to focus on their PS360 projects, so for other ones they'd need to find another publisher in a pretty early state of development. Given Platinums track record (in the sales department), that might not be that easy.

High Voltage on the other hands afaik only have created and released Wii IPs (this gen) so far, so it frankly is a pretty conservative decision to green light the next installment of the biggest one of those.

TheGameFather: Madword on Wii was a "steaming turd"

Misnomer, probably. Since M stands for Mature.

Would you rated it V for Violence? Doesn't sound too good.

They are just putting sex, language and voilence in a group and call it M.

Sega wouldnt publish the game in Japan so they just got another publisher

And i am never going to buy a Sega-game on PS3, unless i get it used

I believe HVS only had one game for the Wii (unless you count games like Dora). Saleswise The Conduit is actually the lesser of all IPs released by Sega for the Wii. That said, I think it sold the longest without a price cut.
