Hmmm.
Story in MN today is that Poland is definitely out - replaced by Turkey which would run in a September date. FIA Promoter are struggling with Croatia to find a suitable date that doesn't clash with the height of tourist season. So looks like it won't happen now. Also for NZ, Ciesla said the teams won't support that extra travel/expense as a 14th round.
Also Wales GB and Catalunya are likely to switch around on the calendar. First six events of the season will run in the same order as 2017.
