1d mark iv instead of a 5d mark iii

Thanks for all of the reply's, they are all very helpful. I find it interesting that a camera released back in '09 can still hold its own to the 'next generation.' That is either a testament to the 1D series or a testament to the lack of progress. I believe the 1D series is just that good.

Wasn't the 1dM4 released for around $5,000? If so, it has held is value very well.
