Rock Band Pro mode is all about potential. It’s about the individual player’s potential to move on up to the next, optional level of difficulty in the game, and, eventually, the player’s potential to make real music with a real instrument. And as Harmonix reps told us, it seems “designed to show the potential of what the music category can do in gaming” — if anything can answer that question of whether music games can translate to the real world, this mode will do it.
My anticipation for the new challenges inherent in Pro Mode is at a ridiculously high level. It’s like taking Expert in Rock Band 2 and then pushing it over a cliff.
But it’s a really awesome cliff.
