Well I don't know if they were INTENDED to be a one time thing, but in mid-2009 the Monster Hunter development crew split into two, one for main games and one for Frontier, and since then the two haven't co-existed very much. I think if they had stayed as one team we'd have seen a lot more crossovers by now.
