So according to the official Remote Control Productions site, La La Land Records will release Steve Jablonsky's score, so we can expect it on JUNE 23 or maybe a bit later. And unlike AoE, this score has already got a label to be released so there will be no issues or big delays, and ofcourse CD soundtracks!

Here's the thread from RCP

When a CD is announced here, there's 99% chance it will be released.
