Yeah it's not in the press releases but someone leaked it a while back. Pretty good list and includes some deep cuts. Defender 2000 is probably the biggest omission (understandable since rights are split up but still disappointing). Would have liked to see some of the old Windows 95 era stuff like Gridrunner++ since those aren't really commercially available anymore but I'll deal.
Also worth noting that the Gridrunner remake is done by DE, not by Minter and stays mechanically close to C64 version. If you want Minter's own remake, I highly, highly recommend getting Minotaur Arcade Vol 1 on Steam.
