will Navi have a VRAM Stacking version of Crossfire? The New NVLink from NVidia allows for VRAM stacking.

Will crossfire for Navi (or what ever it ends up being named) allow for VRAM stacking? NVLink allows NVidia cards to RAM Stack (I'm not sure about GT and GTX cards, but RTX cards can RAM stack when bridged with NVLink). I would like to have upto 4 Navi based RX 3080 8GB cards and get 32 GB of VRAM out of them in one of my future builds. The freaking Titan RTX gets 24 GB of GDDR6 VRAM and can be stacked to get 48.

RTX cards do not stack graphics memory.  That feature of NVLink only works on professional cards, for professional software.  You cannot combine the memory of two GPU's and use them for multi-GPU gaming.
