Garry's Mod "New" Garrys Mod Game - S&Box - Gamemodes

Hi,

so I'm very interested for the (hopefully) upcomming game S&Box.
I don't know if you have heard of it, or not.
It's actually not Gmod2, its a new game series which have maybe some aspects from Garrys Mods.

Some search shows, the last commits(changes) are from 09 / 2019, but on the facepunch devblog 2019 it contains the string

"Next Year
I'm hoping we'll have something to show Garry's Mod fans next year. If not I've wasted another year and I'm sorry."

I think something from it, or maybe the full game will be released this year.
So what you think about that game and what you think, how long does it take to release new gamemodes like RP or TTT?
