FAQ for Rocksmith 2014 notes that the game will support all DLC from the original Rocksmith as well as its on-disc tracks. Speaking to executive producer Nao Higo at Gamescom, we've learned that there will likely be a few tracks that don't transfer. Higo told us that Rocksmith 2014 will support "most" of the original game's songs, though licensing issues may prevent some tracks from making the jump.
"We're still working out the licensing on a couple of stragglers," said Higo. "We want to get to the point where we can say [all the original tracks will transfer], but we don't want to lie to you, so right now we're saying most of them."
Rocksmith 2014 will launch this October on PC, Mac, Xbox 360 and PS3.
