My daughter being too rough?

My daughter is really tough, and she likes to play fight with my husband. She's always karate chopping something. She will be starting preschool next year and I was wondering how she will be with other kids her age. She has friends that she plays with now, and she is by far the rowdy one. She's like a little boy! She's not mean, she dont hurt anyone on purpose. So I guess my question is, has anyone had a personal experience with anything like this? How did your rowdy one do in school? Im worried she will be too rough with the other kids, how can I stop it before it starts?
