If I am 5'11" now at virtually 15 years old... can I be 6'2" when I'm older?

This has been bothering me considering I haven't grown in the past three years. I was projected to be 6'4" when I'm full grown, but I haven't felt the pains that initiate such an event for so long. Have I been stunted? I'm healthy and active; I'm a martial artist and a track sprinter and my parents are rather tall.. so why did I stop growing?
