In conversations with Tim I've learned that Ring Engineering has many new high-quality recordings in their possession, and that work is beginning to create new prime mover files. This will be welcome news to all of us diesel users, as the current Railpro prime mover files leave a lot to be desired.
Confirmed upcoming releases (no idea on release window...could be a while):
-GE Evolution 12-GEVO (for ES44 series) (already in beta, but got put on the back-burner to focus on hardware...HC-2 revisions and CI-1)
-GE Evolution 12-GEVO-T4 (for ET44 series)
-GE 7FDL-16 (Dash 9, AC4400
-EMD 710-G3B (SD70MAC, SD70, SD75)
-EMD 710-G3C-T2 (SD70Ace)
Unconfirmed but hinted at:
-EMD 16-645 Roots
-EMD 16-645E3
-EMD 16-567
These take a while to do, so I wouldn't expect them to be released quickly. However, it is nice to know that we have some good, high-quality sounds coming our way. From what I've heard of the GEVO beta the rest of these recordings should be awesome.
