Geez all this $4500-$5000 is complete wishful thinking, just like when everyone thought the 5D3 would be $2500, it's what they wanted it to be. The 1DS3 was was like $7k or so when it was released, I think this new high megapixel cam will be just as high. Canon charged it before and got away with it, they're not going to sell a 46mp cam for $4500 out of the kindness of their hearts. Just think about that figure, 46MP, no way that's going to be a reasonably priced camera.
