I think we can safely assume Daken and Laura will show up in other books. In fact I imagine the reason X-23 was cancelled over Avengers Academy (which has lower numbers) is that they figure they can get X-23 readers to pick up AA for Laura, this getting one book with overall better numbers.

I have no idea why X-Factor and Thunderbolts aren't getting cancelled. Presumably Jeff Parker and Peter David know where the bodies are buried.
