Dog gone it K.J.! There you go going all logical on us.
I have a D4 on what seems like eternal backorder and I am really starting to contemplate cancelling and just buying another D3s and saving a couple grand.
Since I shoot sports & action (RAW) I was really interested in the improved buffering and the low-light image quality. The reports I am reading seem to indicate my D3s is up to par with the new D4 in this and other aspects.
I just bought 4 Lexar 1000x 32G cards and to be honest the new Sony exclusive XQDs & reader are a big concern for me. The D4 exclusive battery & charger doesn't help either.
