Costco's two-lens D600 bundle (which also includes the WiFi adapter and a 32GB SD card) is now down to $2390; that's $600 less than I paid on October 23rd (that was the second D600 I ended up returning; the first came from Amazon). All of the reduction has come in the past few days; I don't see anything similar happening with Canon. The Amazon kit with the 28-85mm has come down $700, but they've left the "Body Only" price at $2K, which seems like an accounting trick to me.
I can't believe this was the original plan, to cut the kit price by more than 25% only three months after launch.
