Well, the benchmark showed off the high allagan gun and primal weapons are confirmed so I don't think it is unlikely that they will add soldiery/poetics weapons. As to whether or not they will still be around, Idk to be honest. They usually change it up before the patches, but there are still going to be people within the 2.xx series and people that won't have Heavensward so I'm really not sure what they will end up doing with them since the new tomestone will probably be focused on lvl 60ish gear.
