Not posted since ATC, but still reading! I'm sharing what I scraped off the internet. Found a brief comment on the PlayStation blog from the game's producer Matt McKnight: https://blog.us.playstation.com/2019/05 ... this-year/
We’re incredibly honored and excited to announce Ghostbusters: The Video Game Remastered will be launching on PS4 in 2019. All of the in-game videos and cutscenes were found on a hard drive in storage from one of the original creators and remastered in 4K. The great storytelling and audio has all been preserved while enhanced textures and lighting complete the package.
Suggests no new content, but a solid framerate at a high resolution with more lighting effects (and no janky PC controls - can we have proper mouse support please?) will still get my money.
