Other retail stores (Best Buy, Target, Wal-mart, cell phone stores, etc) got at least some shipments over the weekend, did they not? Perhaps some golds were included in those.
Extremely few. I doubt they got enough phones to make any significant difference in the overall numbers.
Totally anecdotally, I reserved a black (sorry, "space gray") phone at Target on Wednesday as a backup plan, in case I failed at the Apple store. They still haven't told me it's ready.
From what I've heard (hooray for rumors!) non-Apple stores are getting just a handful of phones, while Apple's stores are going through hundreds or thousands.
