He is not saying they are in a burnout. He is saying that there is a high chance of it happening given they have so many projects.
Personally I am more in favor of seeing one game progressing fast than 3 slowly. I don't think I saw a team reaching success by juggling multiple games. They all had pne good pitch they worked on.
Like here, I feel that this proof of concept would have much more content if if wasn't one of many projects. Too bad.
That said the idea looks cool and different. I'm thinking of subscribing on Subscribestar (F patreon) but I just don't know how often this will be updated given the attention is spread amongst other games that I am currently not interested in.
Hopefully an official incest patch will come out like for their other games.
Unfortunately i've seen far too many times when devs take on too many projects at once, in the end all of them suffer, slow update schedules, lose interest in one or more of the games, and in the end say fuck it and they get abandoned.
Better off looking at the most popular 1-2 games and drop the rest, keep both of them on a semi-regular update schedule, rather than all of the games suffer, never take on more than you can handle
