If CW is using the Euro version as the backbone for the cut, maybe See No Evil is employing the theatrical or extended version (and giving preference to the relevant soundtrack).
Either way, it seems compromises will have to be made in the process and it'll be interesting to see how each one is tackled. I get a feeling that, at the end of the day, the preferred version will differ on a fan-by-fan basis - as they already do with the theatrical, extended and European cuts.
