I mean the comment above says Hex would release the update a couple of weeks after announcing it. And to be sure you can also check the post from hex. So he did maybe not promise that the update will be out in three weeks but it's been 7 months already and the situation doesn't seem like it has changed in any way. Also yes I agree the developer team or maybe solo dev does make enough money trough patreon alone but then why delay the update so long and not communicate anything about it? I just hope he fixes the situation soon what ever it may be and if the manpower is a problem there's enough coders and artists and maybe even 3d modelers out there looking for work.
