In recent history, the trend of peripheral-based releases has fallen short of sales expectations. Internet-famous Wedbush Morgan analyst Michael Pachter -- along with others in the field of "professional guessing" -- recently halved holiday sales predictions for Guitar Hero 5 and The Beatles: Rock Band; after both fell short of initial sales predictions.
According to Cowen Group analyst Doug Creutz, the falling projections of peripheral games reflect both the casual consumer's decision to reduce spending on games, as well as the possibility that gamers are losing interest in the played-out rhythm genre.
When contacted by Joystiq, Activision refused to comment on the matter. With no less than three new rhythm titles on the horizon, we presume publishers hope the trend of sluggish peripheral-based game sales comes to a screeching halt; like the days of disco music and, apparently, outlining the objectives of major marketing campaigns.
