that's what I have heard... BUT, I don't know if this is really true?!
2 weeks ago I was sure that there will be no WP

All I really know is that lizard green will be offered in 2019 (for 911).
Hard to imagine that this color will be offered on the 992. So, Porsche will have to produce more 991.2 RS.
Therefore they will need the filter (for the EU)....
