other then that what you said seems like the case.
New event items don't get allowed in until a later patch, ie Snowman and the Horse Kabutos. Snowman outfit will never be allowed in, because you CAN get it again. It's tradeable. You can stock up on them, give them to alts, whatever. So that will never be allowed in.
