I heard the alternative g-f#-e-c# in many recordings, do you mean that? Trifonov also played like that in 2010 Chopin Competition. g-f#-c#-a# seems and sounds weird to me, and it's very difficult to play also.Henle prints f#-e#-c#-a# and says this was the autograph. The other version (g-f#-e-c#) appears in the English and French first edition.
