I'm still at "processing" as of 8:43 Central time on Tuesday evening.
I'm in the same boat. It is supposed to be here tomorrow before noon, hasn't shipped yet. Except all three 32GB sets of memory from Amazon have shown up well before the iMac.
What do you order memory wise? I've been eyballing Crucial, and they haven't posted any memory for the new model. The memory they're selling for the 27" Retina iMac that was marked as "Mid 2015" was selling for around $160 for 32Gb. I was figuring what they sell for the newly released one would be around the same. Basically, I didn't want to pay $600 from Apple for 32Gb. I also saw some other company is saying this 27" Retina iMac will actually support up to 64Gb? Apple doesn't say that.
Anyway, back to my shipping... For the record, I ordered:
- 27-inch iMac with Retina 5K display
- 4.0GHz QC i7, TB up to 4.2GHz
- 8GB 1867MHz DDR3L (2x4GB)
- 3TB Fusion Drive
- AMD Radeon R9 M395X w/4GB
So it's custom. I noticed when I went for that chip, the shipping changed from like 2 days to a week. So I knew it was gonna take a week, even though I didn't like the idea.
This is what my order says for shipping: "Available to ship: 3-5 business days / Delivers: 19 Oct, 2015 - 21 Oct, 2015 by Next Day Shipping, before noon"
I ordered it about two or three hours after they first went up for pre-order on Tuesday the 13th. The 3-5 business days ends today (Tue the 20th), that's the 5th biz day. In theory it could still ship tonight, but I would be surprised if it still happens.
I live right outside of Dallas TX.
P.S. It's my first ever Mac order. Ever - any model.
