Xilinx updated DS890 yesterday and there's a "Kintex UltraScale+ Gen 2". Nothing too exciting. It's just a bigger Spartan Ultrascale+, still on 16 nm. Has the hard memory controller, Gen4 PCIe, Versal derived configuration (platform management controller). Hope you don't need fast LVDS because HPIO is replaced by XP5IO and HDIO is LVDS RX only, 250 Mb/s max. XP5IO also means the end of fast 1.8 V IO.
Edit: XP5IO can do LVDS15, missed that.
