Crikey I'm gobsmacked at the panic!!! So you buy a D300 a new model comes out and all of a sudden you need to get the new one????
If you were happy enough to spend a K on a camera surely it's going to last a few years at least???
OR more money than sense?
Sorry if this sounds insulting but I can't get my head around the panic that Nikon may dare do such a thing, it will happen in under a years time so what the hell.
Can't understand why it's not the D400? So to my mind it wouldn't be a progression from the D300 but a new target audience!
