Honestly, I think all the NPCs (Karl, Grahdens, Lugina, etc.) will get one. I don't think any old units will get them becuase it's either all of the old units or none of them since all the old units will get 7*s eventually and it wouldn't make any sense for only some of them to get them. I wouldn't be surpirsed though if Gumi goes the normal route and just gives every unit a dream evo like they did with 7*s. Also, maybe the old batch units (Feeva's batch, Colt's batch, and on) will get Dream Evos. A unit can get a dream evo even if said unit's story is finished as long as a major life-changing event happened if said unit's story. This is all speculation though.
