Just noticed this thread…
For the record (and I did post this elsewhere as well), the deletion was a mistake. I received a mail with information about the kickstarter under embargo (such a thing happens on occasion). Silver posted about the kickstarter while the embargo was active and I deleted it because of that.
I understood after I did that, that the developers had decided to break the press embargo themselves and publish the date, but not the time, which would have allowed us to do the same and which Silver has done, although he did not know about the embargo.
Looking back the deletion of the post and thread was a mistake, but as it was already close to the end of the embargo time when I found out it was a mistake and that undeleting news posts require a manual database change (which are a bit cumbersome), I figured I'd just post the official news from the embargo mail instead.
That said, I think the forum thread can still be undeleted, but probably it is a moot point by now.
