I've not heard any talk about adding more items.
I was kind of hoping that Patch 8 would come with a bunch of items to help support the new subclasses, but it doesn't seem to be the case.
Which is a bit of a shame. Not only would the added variety be nice, but it could help make the new subclasses feel competitive (For example, Death Domain Cleric is cool and all... But Radiant damage has way more items that empower it along with the whole of Act 2 that is full of Necrotic resistant and Radiant vulnerable enemies... So it's like, sure I could try to new shiny subclass... But using Light Domain is just way stronger)
It might be that we simply need to rely on mods to add in additional items.
