i dont know where you buy.. but here i can get a nikon 24-70mm f2.8 for 1499 euro.
and a nikon Nikon 70-200mm 2.8G AF-S VR II ED would cost me 1799 euro.
if i buy the latest canon models i have to pay 700+300 euro more (the same reseller).
I'm looking at current prices on bhphotovideo.com. For the two brand L lenses that I have, the 135mm f/2 and the 35mm f/1.4, I would pay about $300- more per lens for the Nikon counterparts (10xx vs 13xx for the 135mm, ~13xx vs ~16xx for the 35mm). My 85mm it should be a wash because I have the Sigma.
But this debate is really beside the point anyway. The point is that an incremental technology difference in the body will make much less difference to your pictures than your glass. If you're choosing based on who has the best technology, go with Sony, but if you're shopping for a system, then technology is only a small part of the picture.
