Earlier today I tried a couple of longer shots (40% EBF) with a Guatemalan Geisha (roasted by Hasbean), ground on a good old fashioned large conical. They came out at 21% and 21.7%, both very tasty but the second was sweeter and tastier. If I had any more of it I would have tried finer again. (Although I liked previous shorter shots, with better mouthfeel, even more).
Looking back at the article by Matt Perger: http://cargocollective.com/mattperger/the-ek43-part-two, the EYs given there don't seem to make sense, as if they've been calculated with different versions of the software, or different preferences perhaps. Recalculating them using the final version of ExtractMojo (3.0.0.15) set to default parameters (which I believe is consistent with the other recent versions of the software) I get 22.3% (instead of 23.12%) for the EK43 shot and 21.3% (instead of 20.56%) for the Anfim - very much narrowing the gap between them.
This is not to say the EK43 aren't tastier, I cannot comment on that.

Im a little confused .. your not convinced by something you tried or not tried ( ek43 ) - Its really isnt all about numbers , and you may not like my shots and vice versa .. Ive pulled highish EY shots on roburs and other bulk grinders . ( some tasted blind ) and its only my opinion but they i preferred the EK shots . Plus some were just nasty ...but there are other variables at play here too, ( roast level, water , pressure , baskets , what you measure it with and personal taste preference )
Plus i can push EK to 24% with still espresso strength ( 9 tds ) and it still be sweet and tasty ( again to my mouth only )

The friggin' end of the year?

It looks like I have to order a HG-1 for the meantime.

It is frequently asserted that using the EK43 leads to higher extraction yields. All I was saying is that I have yet to see any convincing evidence that this is actually the case (at least when brew ratio is kept constant). I fully agree that it doesn't matter very much.

I am unsure that the claim was that the Ek was the " only " grinder capable of higher extractions yields but that it achieved higher extractions 20 plus that were still balanced and tasty ...

I'm not disagreeing with you. The article by Perger though, for example, (http://www.baristahustle.com/the-ek43-part-two/) does claim to demonstrate that the EK43 can give substantially higher extraction yields compared to some other decent grinders at similar brew ratios and when dialled in for best taste. The numbers in that article are not self consistent however, as is also pointed out in the comments. If the numbers for dose, beverage weight and tds are taken to be correct, and extraction yields calculated on the same basis as for the Anfim, then you get 21.49% for for the EK43 rather than the stated 23.12%, which is still high but not particularly so for 22g->51g.

What is the price of this grinder?

It looks like they ditched the red:

Seems they have changed the grind adjustment knob, portafilter holder, grounds tray and done away with the wood accents as well. I wonder if there has been any approximate release date yet? There hasn't been much info released other then this thread.

Thank goodness too, I thought it looked like an unpolished concept with all those differing colors / materials. The one pictured here looks far closer to a production model than the other did IMO.
