No they wont.. cloud computing is already mainstrean and more than 65% of businesses don't even use any cloud services for business purposes yet so they will only increase in value, especially good cloud domains
VR will grow Im sure, but not to the extent that cloud computing will, cloud will be used by most businesses, irrelevant of what industry it is, where as VR will be limited to certain industries
Good VR names will still do well but its just maths that there will only be certain amount of businesses/industries after the good VR names
