From what I just found afew minutes ago,it seems most likely next year in G4 the new weapon classes will be added.

Also it seems that the original Flagship Monster for G2 was possibly going to be a Fanged Wyvern or some type of Wyvern but,there isn't really any details supporting it,though that is the only class they haven't added from the 3rd Gen to Frontier.
