I think this article gives a pretty good idea. Interesting food for thought, at least:

Here's a portion:
>If indeed Christ proclaimed the gospel in Sheol/Hades to those who never heard in the Old Testament age, that would explain how “God overlooked” their ignorance. He didn’t excuse it or ignore it. He deferred it until the time his son would give them a chance to repent. I argue for a place in Sheol called Hyperidon (Greek for “overlooking”), distinct from Abraham’s Bosom and Gehenna, reserved for those who neither received nor rejected the Word, but simply never heard. God overlooked their ignorance until the proper time, when Christ preached to them.
>But notice how things change with Paul: “God now commands all men everywhere to repent.” By one interpretation, this would seem to say that, at some specific point in salvation history—Christ’s death? Resurrection? Ascension? Pentecost?—God made a heavenly decree that, even if in the past he overlooked ignorance, now he wants all men to repent.
>So, say you’re a 60-year-old Athenian in AD 25, prior to the fulfillment of Christ’s mission. If you died then, you’d still be under Old Testament rules. Your ignorance would be overlooked, and after spending five years in Sheol, you’d eventually see Jesus come down and preach the gospel.
>But if you survive and live past that point, now you’re under new rules that you must repent or be damned. This is true even if you never hear the gospel. Well, lucky for you, you made it to 80 and heard St. Paul preach. Or you didn’t, and you along with all the other pagans of the world die condemned under the new rules of “repent or be damned.”
>But that interpretation ignores the literalness of the “now” of Paul’s words. He’s actually stating when that “specific time” is for repenting. It’s not at some past moment like Pentecost or Christ’s death. It’s “now,” at the moment of his proclamation to the Athenians! In other words, it’s in the proclamation of the Word that the Old Testament rules switch over to New Testament rules. Proclamation of the gospel makes real and present Christ’s salvation event. Proclamation of the gospel “for you” is an essential moment of salvation history. Proclamation of the gospel is the point at which the Old Testament ends for a person and the New Testament begins.
>Why is this significant? Because it means that anyone who dies today not having heard the gospel dies under the Old Testament rules. God overlooks his ignorance, and he will hear Christ’s preaching after his death. Whether that is in spirit, or at the resurrection of the flesh on Judgment Day can be argued (I tend toward the latter), but the ultimate point is preserved that all people will hear the gospel. This is not a “second chance,” because they never had a first chance.
There's more there explaining some of his reasoning. I'd recommend giving it a read.
