Now I don't know what you're trying to prove here so tenaciously but first read what the others have posted and then reply back. Let's sum it up: Ka-50 saw extremely limited production, it uses obsolete weapons - Vikhr (the russians are probably going for Hermes missiles in the upcoming years), it does not have night capabilities, except for several machines which have been tested with such equipment, but never saw serial production, Ka-50 has outdated avionics not on par with the latest developments in this field of technology. Ka-52 is completely different, it may use Ka-50 as a base but that's it, when you talk about Ka-50 leave Ka-52 out of it, they are two different helicopters with different capabilities and purpose. They might look alike but so do Su-27 and Su-35, this similarity is only superficial, what lies under the hood is important.
And yes Ka-50 might be very maneuverable, it may be able to fly backwards and sideways fast, etc. etc. But before all we are talking about military attack helicopters here so the most important thing about them is to operate night and day in different meteorological conditions, to be able to search for and find targets and to destroy such from a safe distance avoiding getting shot down in the process. Doing so requires advanced avionics and weapons. Ka-50 simply lacks those.
Ka-50 is pretty much dead, Mi-28N and Ka-52 have taken its place and you can be pretty sure there won't be any new Ka-50s manufactured.
