The original announcement said the merger would be voted on in "May/June". I havn't seen any elaboration of this but I think that that timing also got a mention in a recent ORG presentation.
That should have read "OXR", of course!
I'll try to find it again but I'm pretty sure it didn't mention any specific timing. Being an OXR holder but not ZFX, it doesn't really matter to me. ( the precise timing, that is).
