We already have a Fury and he's black - unless they go with some weird convoluted backstory that links the two.
My comments were, in part, addressed to speculation in prior months about whether Fury would appear and how. The comics character has his origin in WWII-themed books, leading the Howling Commandoes. But a black man would be unlikely to be in a position of leadership in the segregated '40s, and the time gap between WWII and the present is too great for both characters to be the same person (without 'weird convoluted backstory' involving serums and such), so it can't be Samuel L. Jackson's Fury (if a Fury appears at all, that is, which still isn't established).
But you wouldn't need a weird, convoluted backstory to link present Fury with a potential WWII Fury--just say the former is the latter's grandson.
