End of the day, if u just send your prints to normal color labs, whether its a tiff or double that from a d2x or the long hours spent from the conversions to jpegs. All the files will be end up converted into fairly small jpegs for spooling. The compression depends on the operator. Some labs print at no bigger than 5mb. The mega pixel hype is fundamentally restricted when u go to conventional labs. There is no way they would load a tiff to print even if they have the resources. The time is not justified for the business operation point of view.
Unless u send for industrial prints thats another different ball game altogether. If i were u, I rather invest on the optics, better lenses spell wonders on all file formats, sizes and irregardless on a pro or non pro version of cameras. Even technicians in Nikon find it amusing to the pro idealogy of metal vs plastic bodies, if both were to fall from the shelf, both will die. Higher buffer great for fast actions. Other than that unless one cannot decide the moment to press the trigger for the scene it would be an absolute nitemare to be working on files that u don't need. Who is more pro? The sniper or the one rattling the m16? If both misses, both too will fail.
Essentially the prices of digital bodies will come down with the inevitable lineups ahead. Work around your budget and remember good lenses will still have their values.
