I suspect the Trial version is not going to be the completed copy. I mean obviously but....,
Hicks posted a twitter post (I presume from the event) that had the screen read "Pre-Alpha". So assuming this is what's been shown off to the public and the trial version is what's been shown at events so far I assume this isn't some sort of Beta. Which is both good and bad news because it shows some ballsy confidence that the Alpha is good enough it can be the trial version (and from what has been said so far it seems to be the case). But should something go wrong, well they put out a Pre-Alpha build into the wild and your average player might not realize this.
Now the most recent video doesn't state if it is the finished version or not but the article insinuates it's this Alpha version. That might explain the netgun animation but lets not get our hopes up.
