S&box is actually Garry's Mod 2?

Although the game that Facepunch, the same studio that developed Garry's Mod, is now working on isn't called Garry's Mod 2. I am calling s&box their sequel on Garry's Mod. They probably chose to not go with Garry's Mod 2 intentionally. S&box is, just like Garry's Mod, a sandbox that will heavily rely on the modding community. I would like to know what you guys think of s&box, I am really excited for it and they are working really hard on it, the fact that they are using UE4 makes it even more exciting.
