"I have a dream..." where I'll believe any correspondence about a game I want to see come to fruition no matter how outlandish it may be.
Until the developer themselves posts anything about updating this game, why would anyone believe what someone else has to say about it?
I mean, to be fair, I posted a correspondence that either came from the dev or at least seemed to, to the degree that I was convinced it was from them. Likewise, I was one of three people (not even the first) posting just on this board that they had seen it or something highly similar. Heck, on the official Discord apparently there were multiple folks as well, now that I've looked.
Obviously you're right that it's counting chickens before they hatch to assume it'll actually come out on time, or even that there will be an update more generally. Because until the developer releases it it's not released. But I do think it was reasonable for us to try to inform people of something that seemed pretty legit at the time, and for the board to look into it.
Heck, I still think it'll come out by midnight or so in Poland, because that would track with the contents of the messaging.
Admittedly, in 4 hours or so you may well be the one to say "I told you so", and it's not unreasonable to be skeptical either. I just think we're in for a pleasant surprise, all things considered, and if that turns out to be true then that's great for both of us.
