My 2 cents: same time next year, 6D will be on Ebay for $1200 or less.
$1200 seems pretty optimistic, I'd expect something closer to $1500.
Not optimistic at all...in fact, 12 months after release I fully expect 6D to be about $1200, and perhaps even $1100. Read the tea leaves with 5D III price trajectory.
While I too think this is overoptimistic, I hope you are right. For that price, I would face the wrath of the wife to add this as a second body to my 5DmkIII.
I stand by what I say, but remember, its not such a risky prediction. After all, 12 months really is a long time especially in the tech world. People who claim this pricing could never happen would have conveniently "forgotten" by then or remain mum when that day does come... as it always inevitably does.
Importantly, the fall in price would be well managed by the retailers and Canon. That is, a sale here for $1800 first, an ebay deal for $1700 there, a $200 rebate here, a hard-to-pass up "bundle" price there.... it will be managed so smoothly that the early adoptor who paid 2K+ doesn't throw himself off the cliff.
But again, 12 months is a long time. By then, the hot item that the folks here would be defending "will never drop below a certain price" will not be the poor 6D (which by then would be yesterday's news) but some new fangled 51 MP EOS 3D. The same suckers...er... I mean fans...will be pre-ordering it at $5,600
