Ultimately I don't think it will matter if Nikon produces a digital rangefinder or not. If they do, it will probably cost a fortune and will be available to only a few.
As for the 50th anniversary F, I would love to see one. However, I imagine that this F will only be available to a few rich collectors in Japan.
I doubt very much Nikon is listening to any of us loyal followers. Funny thing is that many people are begging for a fast, high quality, compact digital camera system. The closest thing to this is the Lumix LX3. Retailers can't keep them on their shelves long enough! Imagine if that compact camera had interchangeable lenses, a built-in optical viewfinder, and responded as quick as a DSLR? I wouldn't doubt for a minute that companies like Panasonic and Cosina (Voightlander) aren't working on an affordable digital rangefinder in M mount as we speak. Maybe Nikon might realize its mistake of not developing a digital rangefinder when it sees the customer waiting list for the Lumix or Voightlander digital rangefinder! After all, look at how they were caught off guard when they released their compact P6000 which was blown away by the LX3!
In the meantime, I have found comfort in my Lumix LX3. Thank you Panasonic!
