Hey Sorce, there will always be c kites, they are just going to change form a bit like the new Airush Vapour which will replace the Lift. Like the Rhino etc.
They are just undergoing a bit of a performance upgrade to make them have bigger depower and easier relaunch.
They may disappear in the future but the current SLE/Hybrids need to undergo a bit of an overhaul to make them as fast as C-kites and as hassle free.
Hybrids and Bows have only been around a very short time and if you compare it to the length of time 4 line c's have been around, you'd have to allow them another 5 years of refinement till we see their full potential.
Ride what makes you happy and don't worry about the future, "The future's so bright, I gotta wear Shades"
Good winds,
