I see talk of an A330Neo for regional operations, probably based on the shorter A338 fuselage.
It does seem over time that both manufacturers have a desperation to offer ever-extended range over the other, at the expense of the far more substantial middle market. Even these terms are being stretched, I've seen more than one account of current widebodies having "too much range", and thus not being efficient, for routes like London to New York (3,400 nm). Wing oversized, MTOW (on which charges are based) too much, etc. The proportion of pax who are travelling more than 7,000nm must be 1% or less of the total.
