The problem with a limited number like that, is that there ARE so many time zones, and certain areas that get apps before others. Also, there are ways to cheat the system and get stuff earlier than when you're supposed to. That could mean that by the time it's normally available on the West Coast of the U.S., the free downloads are all taken up...
I haven't seen many download numbers, but despite the people waiting for this, I have to think it will take several days, at least, for them to reach 100,000 downloads. Maybe I'm way off and it will happen within hours, but I'd be really surprised.
