Back in our map rotation event in February on Mittelfans, Gnome and I uncannily predicted operation Wildfire to come on the exact night it did.
A new operation means a new content update for CS:GO - New operation map group, possibly , and much more. Wildfire introduced coop missions with a ton of new content. I'm curious to see what the next one will hold.
That said: I've made this, out of all the research conducted through deadlines revealed through the CS:GO workshop map group.
It will most likely be in November. But the chance of it appearing in October or December is somewhat possible.
