Oh my God, people. It was a one day sale on eBay from Adorama. Many of you are supposing some grand Canon conspiracy. I just read it as Adorama overordered and are clearing inventory for both the D600 and 6D. It is just ONE retailer for just ONE day! All the presuppositions about Canon's demise are silly.
I have tried to point this out to people in this thread several times (as have others). It's funny how that goes and rather telling --- all these people continuing to reply to this post, no matter how many point out the fact that it was a ---1 day sale --- people read the OP and I guess they assume he works for canon or something because they believe it without question. What it really shows me is these people are not in the market for a FF camera, much less a 5d3 because if you were you'd be paying attention to what the prices are!!!!! Are deals gonna pop up? You bethca! Sandisk just had a great instant rebate offer on CF cards, does that mean SAndisk is in trouble? No, it just means they had a sale. Business's do that when they want to spark sales, or like this poster said, over ordered, or ----just simply want to make room for the lesser priced items (like the d600 and 6d).
