Unfortunatly it's not as simple as that.
When a fully working 6.72 exploit does arrive there would be no point updating the menu straight away because all the current payloads in X-Project and other exploit host menus will not work anymore on 6.72.
When a full exploit does drop the only payload that will probably be available will be HEN.
When a decent amount of payloads become available for 6.72 I'm sure we'll make an update for X-Project.
Here is a simple explanation of whats goin on at the moment as I see it:

Al-Azif said that he ported some of the payloads (not sure which ones)
But still, there's hope this will happen sooner than we think
