DK64 & why is it not considered as DKC4

Hi, I was wondering, do any of you consider DK64 to be DKC4 since its technically a sequel? You got dead Wrinkly, Kiddy’s and Dixie’s sibling, references to past games, and even a giant metal island that is the result of the original one sinking at the end of DKC2.

What are your thoughts?
