As predicted 9540 on Wednesday. Its almost like I know what I am talking about.
Why are you so interested in a player trend of a game that has almost no multiplayer by the actual standard of game industry. Relic has release first the single campaign on PC, then will do it on Console and then is going to put in place the multiplayer layer.
All what matter today is the number of sold copy of the game because they are the primary source of revenue for Relic. So first the PC release, then Console release to get the maximum revenue from it and at after that implementing the multiplayer's layer to milk players with in-game transaction.
Multiplayer in RTS games is probably not seen as a viable source of revenue today even it is probably good enough to sustain the franchise once the maximum of copy are sold and so the maximum of players interested in the game already reached.
So Relic will proceed first to sell the game to the many on what matter the most for players: The Solo campaigns. Then, and if the game sold well, they going to release the multiplayer layer because there is no reason for them to put the extra effort to release it first if it didn't attract enough players.
