Regarding the new upgrades, the answer is no, for the sake of consistency. The upgrades are new, unfamiliar to most, and that spells disaster for competitive events. They *ARE* legal in the Narrative, as are all Wave 4 models.
Speaking of Wave 4 models, Aionus is the exception to the rest of the Wave 4 models, but for good reason. He is not a new model, having been released early. Most of us have familiarity with him, or at least have been given a chance to get familiar with him. In that context, Maht and I can see no reason he would not be allowed.
