Hong Kong already has a plethora of cases available, including the same bright yellow imitation SGP lacquer case that I was using for my 4s, for about US$7. There are also dozens of manufacturers offering screen protectors, though I bought a cheap one just to hold me off until the Power Support ones are available.
That said, there are no accessories that would require the data/power connector. No adapters, no cables, and no docks. Apple has apparently kept the lightning connector under tight wraps, and the unlicensed manufacturers have not been able to reverse engineer them yet. This may be the reason the official Apple products won't be out until next month.
I've ordered a cable and an adapter (as well as an iPod nano) online from Apple already, and expect them to come one by one starting in 3 weeks or so.
