What comes after X-men first class?

i know that there will be ( The Wolverine ) next year , but i just went and saw first class and i'm wondering if there will be another movie for that class or what? oh and i want to know , mystique's son (Night Crawler ) who's the father , my sister and I are guessing the devil looking guy in first class mainly just because they have the same powers and tail ... but yes please and thank you!
