They have been pushing back the release date for 2years
It's hard to believe they don't have it figured out yet.
Can't say I blame them though. Think about how much this sport is picking up, how many more sets of cast and forged pistons are flying out the door every month, now think about how they are probably just now starting to make some good profits off each sale, now that all the equipment and R&D for the diesel pistons is paid for(presumably) now consider bringing in a product that's 2x the cost, all the way around, to produce, to purchase, etc...while at the same time making all the other options available, in a way, obsolete. Not saying that is the real world truth, but a possibility, and on paper, to a corporate bean counter watching and calculating all the company beans, the prospect of loosing sales to monotherms looks like a reality.
I would hold out for the monotherms if they were on the market. Would you?
I know everybody says they are too damned expensive and they wouldn't consider it, but I bet, if and when It comes down to it, when the steelies hit the market there will be a big initial wave of purchases, then the waiting game of waiting for public/community feedback (while MAHLE has considerably less sales) then there will be a small percentage of guys that will pick up a set, then there's the guy that has to have them cuz his buddy has them, then there is the crowd that doesn't want to skimp on their build, so they wait another year, next thing ya know, the aluminum pistons and all the equipment needed to make them won't be making money anymore and MAHLE will be getting way less profits trying to recoup from setting up for the monotherms manufacture. For MAHLE, releasing the monotherms looks like a risk, rather than an investment/benefit.
And because of that, I don't see these pistons ever coming to market for mass production sales
That's just my 2
