Gave into the temptation to start a Nikon 1 thread - the original Nikon mirrorless
I hope Nikon learnt a lot since then and manage to provide a system that keeps Nikon users happy. The lens roadmap will be a key factor IMO - and ensuring enough lenses are released to dissuade Nikon users from leaking to Sony, Fuji, and Canon (when Canon gets around to releasing theirs). I'm assuming the new mount is backward-compatible (but how far?).
