Did kabam say what kind of Shards we can use the plumes on?

I'm not sure I want phoenix. So I was wondering if they had said when the shard trade in will be available, what kind of Shards they're going to be and how many per plume.

She got great damage and safest zola counter
With Phoenix you have to start a combo before you can do the stun thing, so how are you finding openings for your combos? You have to intercept or punish heavies/specials. That's not hard but not the safest way to fight him.
There are also champs like Bastion who can just parry him, land heavies, and do red numbers on the special.
Again, I like Phoenix, and the stun/incinerate thing is very satisfying.
