Here's my speculation:
But seriously, I don't really understand why you guys can't tell us the reason for the shut down. All we know is that Square Enix is involved somehow with it. I can understand not wanting to talk about the future of the kickstarter until it's set in stone but isn't their reason known to you? The update on the main page sounds like it is. You've said the speculation hasn't gotten anything right. So they didn't put a cork in it because it made so much money, or they thought you were making money off it, or you didn't get a license? Those seem like legitimate reasons (albeit paranoid reasons) for SE to stop it but apparently they're wrong. So why then? I really don't understand why you can't tell us that.
