How likely to be on next steam sale?

Title* I didn't bother to look at the game back during the summer sale. I knew it was going to be good after a certain amount of development time and after a certain price drop to deem its worthy-ness.

Regret missing out on it on the summer sale and the one in august too :(. So how likely will this game be on the upcoming steam halloween sale? :D I'm anxious to play it. Tried it for a bit on family share but the user is 95% of the time on a steam game :|

Thanks in advance for info.
