5D III isn't like 50D was back in the day. 50D when it came out wasn't ridiculously overpriced for what it was.
I mean, I love my 5D3 and this is by far the best camera I've ever owned but I think considering what D800 is, and how much less it costs, 5d III price is too high.
I believe Canon is playing a game here, widening up the price gap for more upcoming cameras. For example like making their entry FF be around 2 grand. And then releasing a 3D series or maybe another 1D with high MP closer to 4500 or 5 grand.
