I would not be surprised when they introduce the Miller or Atkinson cycle.
This would further reduce the consumption/emission and in combination with the variable valve timing and lift, they can allow their ICEs to run efficient over a much broader range of usage regimes. Another possibility would be the variabele compression ratio enabling cylinder head, further enhancing the efficiency over the entire range of regimes while further enhancing output at high regimes.
Nevertheless, when they would do this, it's a serious effort/investment to introduce this on a soon to be outdated technology.
