Terrible twitter is terrible.
This twitter feed is probably the worst twitter feed I've seen of any gaming company.

Way to fail at company twittering Obsidian. I can only hope that your twitter fail doesn't carry over to game fail.
Addressing the first question: it depends if this game is any good or not.
If the game is really bad then sales will be terrible.
If the game is good then sales will be good.
