Question on Set Bonuses - New, Old, and Unassembled L55 drops

[BuriDogshin]

We have seen on the streams that there will be six-piece set bonuses coming with 3.0, with new bonuses at 2, 4 and 6 pieces. My questions are about old (L55) set bonus pieces and the Unassembled drops that provide them.

 

First question:

1) will old set bonus pieces be converted to providing the new set bonuses, or keep the old ones?

 

If the old L55 pieces provide the new bonuses, I have two follow-up questions:

2) will old L55 set bonus pieces work with the new L60 set bonus pieces?

3) Will L55 Unassembled Waist and Wrist pieces provide a set bonus when redeemed, like the L60 ones?

 

Thanks!
