Sorry, I owe you my apologies.
FJ: Thank you, yes, it is about the "Early Prototypes" of the interposer. We were informed (material news) that the plan is to send out prototypes in Q3, and we were not informed that this changed.

Sash: There most probably will be no further NR about prototypes as long as there is no signed contract - due to NDA's in place for all the sampling.
I have a source telling me that they received interesting material from Denselight (here in Europe!), but absolutely right, this is all unofficial (so you can call it BS) and I, therefore, I should have not mentioned it. 

But I am also sure that the SP can react anytime "soon" on the right events. So to claim that there will be no sales and therefore no SP reactions this year is - sorry - BS.
