Mine arrived with the firmware update, so I don't know how bad the focus speed was at its worst, but it's still bad for shooting movement (have lost a ton of toddler shots). That said I love shots that do turn out (in a way I never did with my old D70) and been happy enough to avoid upgrading. Only other complaint I've heard is (mostly speed) performance compared to the similar T4/T4i, but that enters the mini dSLR v. mirrorless debate.
Anyway, still quite happy I jumped on the sale. Assume everyone saw the price & market on the new version? Makes this sale (which is still out there) all the more attractive.
