I reckon main airports like LHR, FRA, CDG will still be served non-stop. They are not stupid. But for places to which they have less traffic (possibly MUC, HAM, BCN, MAD, VIE, ZRH, FCO, MIL, etc) they can use OK flights and offer convenient connections every day, maybe even ICN-PRG twice a day, which would allow for better connections from Oz, too. They can also offer some of the latter places as direct connections.
The concept they currently use is very inconvenient, and so the OK model might actually work better.
