Not really and not yet. He apparently makes some kind of deal with Cyttorak in Uncanny but that that hasn't happened yet, is tied to Fear Itself, and I haven't seen anything to indicate that it continues beyond the end of Fear Itself.

Not to mention that we'll probably have to wait until the end of Fear Itself to figure out where Juggernaut's story fits in, since he's been seen in three different places in a single week's worth of comics.
