No, it is not. He promised Sq in 2016. Right until december on their website. In january he removed it from the website and never mentioned the game again. He promised 3.0 'in a few weeks' end of 2016. The feature list has been massively cut down, and the weekly schedule comes with weekly delays, and now projects 'in a few weeks'. Almost 9 months later. Its not a one-off mistake that happened years ago. Its a pattern that started in his earlier games (where he had to be fired in order to get something released, which is why he doesnt want anyone controlling him anymore), his movie (which got him removed from Hollywood) and the entire SC project from day one till the schedule of last week. There is no sign of any of it changing either.
And what do we get here? A video about what we will definitely get in 3.0? No. More promises about cool stuff 'later'. Cool man. Totally belief it.
You could stop believing him and just go about your life until one day you read "SC RELEASED! INTERNET BREAKS"
I've found that, if I want something to arrive, I ignore it and try to forget about it until it does; because eventually, you do forget and then time passes and suddenly, it's out.
