But, I was looking up the leaderboard "Top 1%" scores to throw some numbers out. . .and it looks like in recent DLC there are more top 1% scores listed for pro guitar and pro drums than regular guitar and drums. In keys, the regular mode only barely edged out the pro mode. I'm not sure how reliable these numbers are or really what they mean (do pro guitar upgrades make those DLC tracks sell better than the non-upgrade tracks?)
And given that the last 3 "challengers" to Rock Band have tried to emphasize "real instruments" (PowerGig, Rocksmith, BandFuse), has the market really gone in that direction? Has the 5-button party-game style of play been overtaken by the much more difficult pro mode play among remaining players?
