I haven't seen a "grand announcement" yet, have you?
I merely posted that I had seen the block, and estimated configurations and prices. They have tested for porosity and core shift with good results SO FAR. Since several processes are involved, all need to be thoroughly tested. A Perfect design may be possible, but it is not the the only step in the process.
I hope it all goes well, but I don't think and announcement will be made until they have tested under fire.
Give them a break! Better yet design and produce one yourself. Competition would be good.
