I lost my hope on Nikon several years ago. It would be very nice if they became a real player in the video world, but I'm not going to get excited until I see some real announcement. I mean: Canon also has a big booth every year and they haven't delivered anything that could interest me since the 5D3.
If Nikon did a run of cine glass, Sigma style, they could probably instantly have a big following. The only issue is that Canon hasn't bothered making their primes in PL, which might mean that it wouldn't be worth it for Nikon either, but who knows.
