[Update] There's a better deal that just showed up for only $2599 (here).

The Canon 5D Mark III is currently on special offer promotions from major retailers down to just $2975 (as seen here), so my guess is we might not expect another price drop until after January 5th. This isn't as good as the previous $2599 deal a few weeks ago, but if you're looking for something cheaper sooner than later, there's another deal on the Canon 5D Mark III (Brand New USA Warranty) for $2799 via eBay (Click Here)
