Everybody says wait... but can a case be made that buying a D700 now makes sense because? price: buy D700, sell it later, lose $1-1.5k, but buy D4 later when price has dropped $500, and meanwhile get $1k value from D700 -- how much would I really lose? need a 2nd body anyway Background: I am primarily a sports shooter. I specialize in bicycle racing. I have D90 + SB-600 + main lenses (12-24 f4 AF-S, 24-70 f2.8 AF-S, 70-200 f2.8 VR2 AF-S) + backup lenses (28 f2.8 AF + 105 f2.8 micro AF + 300 f4 micro) I want a second body for backup. I'm tired of waiting. I want to own 1 FX body + 1 DX body. FX gives me less d-o-f and allows me to crop action shots better. DX gives me longer lenses. Combination gives me more flexibility in lens length. I plan to buy a hypothetical D4 + D400 eventually. I'm ok with the whallop to my wallet. So how much will a D700+grip depreciate between now and D4 announcement + 6-12 months? and how much will I save on a D4 by waiting 6-12 months? I thought about just renting a D700 for a few races, but a weekend costs maybe $250. I expect I'd get addicted and end up renting it 4-6 times, at which point I might as well just buy one.
