Will black cat be in any Spider-Man movie?

I think it would be a great idea, since the character was not much developed in Spiderman 3 and it would be great to see that change in the next movie, although not being completely faithfull to the original mythology of Spidey.

She will be Black Cat in Spiderman 5 and she saw peter kill his boy friend edie brock. So she become black cat and a half of villain half of hero.

No. Gwen Stacy was not the Black Car. If you look at the history of both characters, they are completely unrelated and separate identities.
