With hype comes danger, and the possibilities are:
1. It's going to turn out like The War Z Infestation: Survivor Stories. Devs get lots of money for what they present, but release an utter crap. The promised features will never be implemented and the devs will abandon the project because they've already earned a shitload of money, so why bother any further?
2. It's going to end up like DayZ. An endless beta and continuously shifting release dates for features. The devs won't abandon the project like The Wa Infestation, but will slooooowly update the game and introduce new things to create the impression of working.
3. It will be everything they promise, best FPS of 21st century. The world will come to peace, people will never have to work again because all labour will be done by robots, and Half-Life 3 will be released as the best game of All Time.
4. Most probable - it will be overall a great game, but expensive as fuck, even more than the newer Battlefields. DLCs will be released for ungodly prices and people will buy them.
