Good news is that the redemption rates change back too, Blue1 Premium redemption rates will now be the same rate as SAS Y instead of SAS C (eg. 16 000 within the Nordics), which IMO makes more sense. Although I guess that also means no more lounge access within the Nordics on those awards without *G.
On business tickets I'd bet that they still earn 200% just like they do on SAS flights that only have M and Y.
