Well supposedly the only way a Chapter 4 would work is if it was new characters after some long timeskip. Or a what-if scenario several years after the end of Chapter 3.

SPOILERS: Supposedly Torotoro is working on something involving Alice I, and the 6-ancestors. It is unknown if it's some sort of Chapter 0 prequel thing or not. But you can learn more about it in the MGQ official page.

I doubt Torotoro, a doujin company is having issues with funding. However it is true that the 3rd chapter is Rogue Translators' last game he's working on supposedly. I expect different games to be made by them in the future. But seeing Rogue as the translator is sadly unlikely.
