Looking at the past, they are almost sure to bring the Sound Track out on CD sooner or later (OST = Original Sound Track) and we were talking about that. Though there's no official announcement (that I am aware of) about another OST coming out, I'd be very surprised if they wouldn't do it sooner or later.

As for the extensions, I meant the scenes that were added in the anime, which were not in the manga. In the manga we didn't see Mirajane trying to burn her demonic arm and we saw far less of their journey from their hometown to Magnolia.
