It'll be bonus tracks. Live songs are for singles and I can't think of a record in the last few years that has had live tracks incorporated into a deluxe edition, it would ruin the flow of the album. I'll probably preorder the bonus/t-shirt combo tomorrow.
Not in STP's case. STP's bonus tracks from Core, Tiny Music and Thank You have had live or different version of songs. They have never released new tracks or b-sides on special editions. Hopefully this time will be different.
That's because they've never had special editions, they broke up before those became the norm. There weren't deluxe editions of Core, Purple, Tiny Music, No. 4, or Shangri LA DEE DA in the United States. Thank You had a deluxe edition, but that was a Greatest Hits album, it wasn't a real album. Live tracks in the last couple of years have mainly been iTunes bonus tracks and on singles (which they've always been).
Scott also mentioned a few months ago that there would be bonus tracks. I know he's not always too reliable but he said it at a point when they were mostly done with recording.
