What K9.3? I see K9.2 there...
Komodo 9.3 is there... but it is slightly lower than K 9.2. Quite a few games have been played also. I strongly doubt that 9.3 matches Stockfish in blitz anyways with only four cores. So it makes sense to me. Stockfish 6 of course is a dead fish now.
On CEGT 40/20 Komodo on 1 thread after 300 games is 66 elo above Stockfish 6, which is more than the likely gain for Stockfish 7 at this level I think. 40/20 is really about 40/10 on modern hardware due to the way they adjust, which is roughly equivalent to four threads in blitz. So we may have a split decision where Komodo tops the CEGT blitz even after SF 7 comes out while SF 7 tops the CCRL blitz list. Of course all of this can change a lot with more games.
Now after some more weeks things have levelled out and the difference between Komodo 9.3 and Stockfish 6 on 1 core is 34 ELo and not anymore the 66 ELO as Larry mentioned above. The difference between them with 4 cores is even smaller 24
Time for 9.4?

Dude, where the heck are you getting 34 Elo from? If you are going to make statements then make them accurately. Stockfish 6 is old news. Comparing Komodo 9.3 to it is a little ridiculous. Here is a real result from the CEGT website page. The time control is 40\20:
Stockfish 6.0 x64 1CPU - 3182 100 + 29 = 63 - 8 60.5 % 3255
Now yes these are only 100 games total. My rating calculator tells me that we have a 74+ Elo advantage over Stockfish 6. Needless to say, a 60.5% percent score is quite the little spanking.
It should be noted that the four core results are problematic. I will copy and paste here what Larry has written concerning Komodo 9.3:
"The selectivity value was raised because one program change made it possible to be
more selective, and 131 tested as the best value in bullet chess. It is possible
that it is too high for normal levels, but there is no evidence for this.
My view is that Komodo 9.3 is a clear improvement over 9.2 on one thread and on
many threads, but it now seems that the MP changes that helped on many threads were
a small negative on 4 threads, so it's not so clear that 9.3 is stronger than 9.2
on 4 threads. We have already fixed this problem in our latest dev version.
Has anyone even bothered to look at the result differences between Komodo 9.3 and 9.2 SINGLE CORE?! I'm seeing +20 in 9.3s favour. Also below is 9.2s score versus SF 6. Not quite as good as 9.3 is it?!
Stockfish 6.0 x64 1CPU - 3182 100 + 26 = 55 - 19 53.5 % 3206
Other than some SMP issues now fixed for lower cores like 4, 9.3 is absolutely stronger. There is far too much hype and paranoia around here.
