Gary Dunn of SEGA Europe has gone on record to say that they aren't necessarily done making mature games for Wii at this time.

"The House of the Dead: Overkill was a profitable title for us. While it had a rather sharp tail at full price, they do bubble away at a lower price point for a long time. You get your money back and a bit on full price, but over the years, if we do the final product return on investment, profits come from the lower price point".

"You've got to push boundaries and explore. I think while MadWorld commercially didn't sell what we expected, I wouldn't say it's game over for mature Wii titles from Sega. We're taking a look at the resources we have now. We have the money to invest in development, we're just considering where to invest it next".
