Shipping Questions...

I ordered my m17x R2 on 9/7, and at that time it showed a delivery date of 9/13. I got a message that it was going to be delayed to 9/17. I emailed the rep who processed my order because he said this was likely to happen and if it did he could put in an expedite. Which he did. He emailed me on Monday the 13th to let me know that the manufacturing dept got back to him and said everything was a go ahead and it would take 3 days to build. So today (9/16) my order status is still showing a delivery date of 9/17 (I have next business day shipping) but the system is still showing in production/not shipped. ARG!

Anyone have any guesses when I will get this thing? If it ships tomorrow instead of today will I have to wait til Monday which would be technically the next business day? That would be a real bummer. Or does who ever they use deliver on Saturdays too?
