D3X 18mp resolution, (FF) full-frame 10mp/10fps HSC
DSLRUsers.Net Aussie forums has a rumour from a friend of a friend:
“I was talking with the photographer who did our wedding last year, and he has a mate going to meet with the big wigs of Nikon regarding the release of a new pro-DSLR. Whilst no designation has been given as yet, it is expected to be a D3X featuring 18mp resolution, full frame with a 10mp, 10fps fast speed crop mode. Cost is estimated to be $10k [Aussie dollars, about $9000USD right now].
Also, apparently a 12-24 2.8 FF zoom will also be released.
This is all targeted for an August release.”
