Oddly, order 61 looks weird, numerically it's in the midst of 10/8 orders but listed as a 10/7 order, which I guess makes sense that they'd receive their 16 GB black before lower order numbers. Still seems odd, though.
In total, I've got 18 4s's yet to ship prior to mine, but only 6 16 GB blacks specifically yet to ship before mine (#72), with a couple between mine and my wife's (#75).
Was hoping a little more action would happen over the weekend, but sadly not. Sigh. Still more waiting.
