Because we didn't want to risk PS3 users getting no content for weeks longer than necessary, we submitted a lot of PS3 RBN content ahead of our normal schedule. Unfortunately, "St. Elmo's Fire (Man in Motion)" came out 11/15/12 on Xbox 360, which means it wasn't eligible for submission at that time.
There were a couple notes about this (indirectly) in the PS3 request thread:
http://www.rockband.com/forums/showt...=1#post4918347 indicated that all PS3 songs inclusive of 1/8/13 had already been submitted by 11/2/12.
http://www.rockband.com/forums/showt...=1#post4918433 explained this was to work around the Sony/Harmonix holidays and ensure that PS3 users did not experience any avoidable delays. It also added "However, if you're really excited about a song that came out this week, it'll be a wait."
