Yes. I recently messaged Squarp to ask about it, and they confirmed that Xp32 cv expander native support is coming to Hapax! It will require a new upcoming module to connect them together (without the need for Hermod+ in the system).
I imagine the module will probably have a port on the front for Hapax to connect to, then the Xp32 ribbon connects to the back. Hopefully, they are able to somehow add a few more cv ins on the front panel as well (since xp32 has 32 outputs, but no cv inputs).
Regardless, once the extra 32 cv/gate/pitch/mod etc outputs are implemented, it will definitely make Hapax the most powerful eurorack on the market imo. Cant wait!
I posted a topic here about the conversation I had with them here: XP32 cv expander compatibility definitely coming soon
