Their latest update said their stretch goals are a...stretch. They are going to try to get in as much as they can, but some of their goals are way off. They are already giving the impression that they may not be able to get everything in at launch.

I wanted to make it clear that our stretch goals are just that, a stretch. We will be attempting to pull in some features and get them closer to launch, such as Primal Packs and the AI deck builder. This stuff was always in the plan, but much further out. And so, we are in the position of deciding what to promise you now to keep the excitement rolling, but not over commit and force ourselves to delay the launch. Because the absolute last thing I want to do is delay getting you into the game, the sooner you have a chance to actually play HEX, the sooner you will realize just how amazingly fun this game actually is.
Also, I'm probably alone here, but their stream on twitch didn't really get me excited about the game. The guy who was playing it made some very obvious mistakes and didn't even really generate excitement within himself.
I am considering going up to the King tier, but I am having a hard time getting myself to do it based on what I've seen so far.
