Was going to mention which US demos went poof, but that already happened. The removal of those demos CONFIRM my suspicious on the length of WiiWare demos in the NA region: 4 weeks if not received well enough, 12 weeks if received well enough.
Despite Zombie Panic's sales boost, the game probably was not significantly benefitted by the demo enough for Nintendo to keep it. Also, it has been said that Nintendo Channel rankings also are considered, too.
So, NEXT WEEK: Lit and Urbanix are on the chopping block. Neither appeared on the Top 20, and while Lit is awesome, I have a feeling that both demos will disappear next week. Play or download them while you can. lilt line would also be in line for the 12-week mark, but the demo failed to stay past the 4-week threshold.
