Notch has always been very good to his employees [1](and seems like a good person on his own as well), I imagine they'd turn out OK.

Thanks for the link. I realized my initial comment might look like I was insinuating he wouldn't/isn't good to his employee, while I was simply wondering how the situation would turn out for them. I guess probably quite well in this situation.
