With the "big three" doing a limited, and probably reducing, number of races each year, the last thing we need is Nys or Ronhaar becoming as good as them: we'll be back to most races being over by the end of lap 1. If, however, they settle in at about the Vantourenhout/Sweeck/Iserbyt/van der Haar level, then we could have 6 or more guys who are genuinely competitive with each other.
The MvdP/WvA battles were a real treat, but aside from them, the Kasteelcross (day befor Benidorm, none of the big names present) was about the most entertaining race I have seen for a while, with a fluctuating group of up to 8 at the front for at least 50 minutes of the hour. A few more names in the top 'mere humans group' as above, and that could be the front of most races.
