Did Adam and Eve end up getting saved? After answering a recent question, it occurred to me to ask: Is there any biblical evidence regarding whether Adam and Eve have been redeemed in some fashion (and are thus going to Heaven/the New Earth)? (Someone to tweak the tags to fit better would be welcome!)
Unfortunately, the Genesis narrative is pretty sketchy about Adam and Eve after they were cast out of Eden, focusing more on their descendants.  We do know, however, that Cain and Abel both offered sacrifices to God.  It's reasonable to suppose that they were taught to do so by their parents, indicating a general attitude of piety.  Whether or not they actually repented and obtained forgiveness is left unclear.

I do remember reading the Apocrypha one time, and one of the books (I can't find it right now, does anyone have the reference?) contains a list of Old Testament characters and commentary on them, and it refers to Adam as "the greatest of all," alongside the great prophets and patriarchs.  While the Apocrypha is not generally considered canonical or authoritative, it's informative at least...
