Questions about PQ rewards after jump

You all know how people expects 'Jump!' to hit around October and how along with it changes to PQ's are implemented. My questions are:

1 - Will the belts we get from the Prison Break PQ be Karma'able?
2 - What happens to the current Rex earrings after the lvl 125 ones are released? Will there be 2 kinds or will the old ones evolve into the new ones?
2 - Are these earrings chaos'able despite being durability items?

1 - Completely untradeable
2- Nothing. You need 50 PQ items from the boss (basically 50 PQs completed) to get the new rex earrings.
3 - Yes
