Wonder what they will be???
That wording is misleading. It implies actual new games for old consoles (like what homebrew devs do, e.g. Sivak Games) or formerly-unreleased/cancelled games from that era being completed and polished/fixed up (like what Piko Interactive does…occasionally).
Those are just ports/remasters. Sure, they may be the definitive versions of those games, but they’re not “new” games.
