Ya-hawn. You probably can't buy it, most people who can won't unless they need it or they're a wanker, the D3[H] will probably till offer better quality for most situations; this will have more resolution that won't show up except in 99% of prints, but probably a marginal increase in noise, and lesser tonality and color.
There really is, ultimately, little reason for this camera to exist except to complete Nikon's product line-up and marketing. I mean, after all, have you ever heard someone bitch about the image quality of their D3[H]? I normally don't harp on image quality so much because it's long past the point where it matters, but that plus video minus some FPS is going to pretty much be the only differences.
And ultimately, what does the leak matter? We've known it's been coming since the D3[H] was announced, but even if we didn't, what does it matter? Even Bill Gates couldn't buy one today.
TL;DR Ya-hawn.
