Walker, when is new PK Photo Black out for sale?

I read of this new darker PK Photo Black, but was curious as to the time it will go on sale since I have an order I may need to send in for some other inks soon.

Will it have a new order number separate from the current PK Photo Black, or is it to replace the current PK Photo Black?



The new photo black will be ready soon. It will be called PK HD
