Well I decided to give another call to Play support and I got some more detailed news (although I'm taking it with a grain of salt). Apparently if you haven't received a backorder email by now, you're not on the backorder list. The customer service rep I talked to also said order time does play a factor. I don't really trust that statement because of what users have said.
The rep told me that because there is a huge delivery list, it's taking a while to get uploaded and that our items could very well be in transit right now. He also said worst case scenario my N4 would get here before Tuesday, and no later.
So apparently the no news is good news thing isn't to far off. Hopefully this is true!
