Mods were closing threads because people were taking them (tweets/even retweets) out of context. The fact that GG is now started to use this account should be enough to say they are moving away from "just a KZ studio".
They didn't start to use now.
It's from 2014. We already "know" Horizon is coming.
So a twitter created in 2014 with no content or update is worth a thread now as a proof? It strength the rumor, only.
But well. People see what they want to see. And when Horizon is out, it will be one more channel to fans. Good people are aware of it.
