Miss Z - Nappa Leather

So I am graduating in May and I have decided I want to purchase my first pair of Louboutins. I really want the Miss Z's but in Nappa Leather. Is there a chance they would be released by then? Should I just bite the bullet and buy them in the patent leather?

My worries with patent leather is that it will crack and that its not as long lasting. If I am completely wrong, please let me know!
