I want to buy a telelense to complete my collection (16-85, 70-300 VR, and Sigma 150mm macro). I was thinking about the 300mm + 1.4x conv. (and Sigma 150-500, but that seems to s*ck in comparision to the Nikon 300mm) but I'm hearing some rumors about a possible Nikon 400mm f5.6 VR. It is also stated in the roadmap of Nikon for 2009-2010 I believe (if it's real that is :p). Is it worth waiting for this lense? And what will it cost? Would it stay under about 2000,- Euro's (about 2700,- USD)? Otherwise I'll buy the 300mm + 1.4x (but... it has no VR :( ).
