Bone Thugs Recording with Who?

One of the greatest groups in Hip Hop history is going to record with K-Fed and Vanilla Ice. It is said that Bone Thugs N Harmony will be working with them on a new album but I do not know for whose cd. I hope the Thugs aren't doing this for pop exposure which they probably are. Does this hurt the legacy they have created?
