It's not going to be a multiplayer only title.
It's not going to be developed by a 5 man indie-studio, instead it's going to be developed by 5 studios at once.
It's likely going to be based on the latest DooM engine, not QC.
It's possibly going to star a LGBTQ female feminist protagonist SJW with blue hair (hint: it's Nyx).
