As I have said before I have personally donated money to Caribdis using Itch, so saying he makes nothing fromthis site is inaccurate. I would agree that he probably makes very little money from this site.
If you double check the release pattern there is usually a changelog and release date announcement, followed by public release approximately a month later. There hasn't been a changelog and release date announcement yet let alone the public release. Following that pattern Caribdis is at least 1 additional month behind.
Now I understand he is nearly done with this one, but that will most likely mean there is about to be announcement for the changes, then roughly a month will pass before the public release.
