It that the right question ? I am sure some networks would also continue to use Microsoft's announcements in this scenario. So, it would be a mess. 

So, I think that the right question is something more like : 

If ARIN reassigned the space, and Microsoft continued to announce it anyway, would either announcing entity be have enough of a critical mass
that the conflict wouldn't matter to it  ? 

I would submit that any address assignments with continual major operational issues arising from assignment conflicts would not be very attractive.  

I also don't think that that would be good for the Internet.
