How do I get datasheets/info for Agilex-9 Direct-RF/Stratix-10 SX?

So if I can't get any technical information, how am I supposed to make a determination if I would want to use these parts in a new high-end design? Or is there no documentation because these parts are "vaporware" - e.g., Intel is taping out some engineering samples, but their genius marketing team is going to push ahead as if these parts were actually real? I miss Altera. I guess I'll just use Xilinx RFSoCs.
