Looks pretty nice, but at this pricepoint, its going to take a lot to convince me over an OR Glide, Duotone Aluula Slick, or several other nice options out there....
Personally, I've never seen a single Core XC wing on the water and never really heard much about it, which is odd since their kites are quite popular in my area. I'd be very open to trying one if they were around.
Looks sick! I want the 3m! 
My buddy loves his Core XC wing. Build quality looks top notch.
