There are no more BCU1525 available until December, and even Xilinx has almost no VCU1525 available either. So anyone claiming to have a big order is fake.
Bittware is the best way to go right now. The XUPVV4-VU9 is available relatively soon and their 300A board around October.
You mean no possibility to order VCU1525 from Xilinx partners anymore (with reasonable lead times)? I mean few boards, not 1000
