Well, it's time, really.
Starcraft came out in 1998, SC2 Wings of Liberty came out in 2010, so a dozen years later and 13 years ago. Even the third part came out in 2015 (yes, it's been that long already!), so about 8 years ago by now. Considering how much ABK is earning on those titles both in money and prestige, it's no wonder another one was due to come out sooner rather than later.
