I don't agree with Wolfeszorn's take 100%. The story isn't the games strong suit, but there is a bit of one there... or at least glimpses of potential.
You're best bet is to seriously stop worrying about when it will come out... Basically forget it exists. At some point in the next few months, you'll see it show up on the latest updates page.
Whether you should wait or not, is entirely up to you. I'll say the same about the vast majority of games... give it a try. You won't know for sure if it is worth it until you give it a try. Worst case scenario is you download it today, play it over the next day or 2 (or longer), and decide whether it is worth coming back or not. The next update likely won't sway your opinion and you'll save some time instead of anticipating a release for a game you may end up hating.
