IF they did more songs, they will release it. It's not 8-Bit Rebellion that there was only one song. It's not possibly to make 4/5 songs and release it only as in-game bonuses, it'll be weird (unless it's short instrumentals).
Comparatively to EDM track, it has a lot of lyrics.
What Steve said in the video?:
"This is like one of the first songs ___ ___ ___ ___ ___ my world and the Linkin Park world."
Yeah this song has a lot of potential. They still can play it later, and if the lyrics was different it was great to use it in some events like The Messenger.
I'm not sure if you fully understand me or you're merging between two things:
What I meant is this:
LT remixes without BID remixes promo ("LT: Remixed") - are part of official release and they are EDM collaborations.
LT remixes including BID remixes promo - are EDM collaborations.
