I missed most of Salnikov, except for the end of the sonata, which was pretty good. But I think he deserved to get the final if only for his impressive Liszt act. The shoulder length hair flopping into his face, the staring towards heaven, etc. And then at the end...most of the pianists took a short bow, walked off the stage, and then in a few minutes came back on for a second bow.
Not Salnikov.
He stood grandly with his hand on the piano as if he had passed through an enormous spiritual ordeal, and faced the audience with proud carriage as if to say, "Applaud me." And they sure as heck did. After multiple bows he walked leisurely off only to come back on to receive his continued due. It was definitely worth watching! So yeah, I can see him in the final.
The Dutch guy I only heard in the first round so I don't know how he did in the others. Sun Yingdi though was one I definitely picked out as not making it to the final.

Guess it's a good thing I'm not on the jury. I really didn't like his rendition of the b minor sonata.
Speaking of being on the jury, how on earth do you decide from among nine outstanding pianists which are the three 'best'?
