I'm not too worried about the next update being the last. I mean if he stop being vague about the status of the game update people would be more inclined to support him.He also wrote (Discord?) that this update could be the last, after which he will give up on the game altogether, so there is (there was?) not much motivation left for him, at best to make some kind of conclusion, or alternatively to leave everything in suspense...
But as it is currently I think people are holding off until the next update drops before pledging support again. We will see what happens then, I suppose.
