Oh I agree- the inertia that these rounds have is immense which makes the idea of rechambering the ar series a non-starter (even though the ar lends itself to it). If there is ever going to be change from the 5.56 to the 6.8 it would have to be because of the wholesale replacement of the ar series as a whole, something that won't happen soon.
Though if it did I can easily see the brits coughing politely as we swap to a .270 round and saying "We told you so..."
