Just like Blizzard, the game will be delivered when it's ready and only when it's ready.
I think that comparing SC to Witcher 3 is very good practice.
Because W3 is apparently one of the best games ever made and Squadron43 will probably dethrone it when it releases since it has what is regarded as one of the most amazing scripts for a game.
I also agree that CIG is exactly like Blizzard.
Since SC started development, Blizzard has only released a few relatively successful games/expansions to previous relatively successful games.
Compare those to the content of SC alpha 2.75 and you can tell why people make comparisons between the two.
I also heard some rumors that Ben Lesnick was being headhunted by Blizzard but he's been refusing any offers due to his overwhelmingly love and support for Star Citizen. True faith is unwavering.
