Except it is already happening; I'm currently consulting for an organisation that does have IPv6 stuff in live use (the.se ccTLD registry). And modifications of IPv4 won't help; any change to the standard that addresses the namespace size requires the same infrastructure upgrades as IPv6 does. What may happen is more and more use of NAT, and/or more and more piggybacking of one protocol on another. But those are kludges, and at some point changing to v6 will be more economical.
Large-scale changeover will almost certainly happen in China and India first, since they have very small parts of the v4 space compared to the US and Europe.
