This is 16GB which is shared with their GPU so it will be interesting to see what limit Apple puts on the GPU for grabbing memory. There are stories that Apple is working on a gGPU so that would free space up on a future Mx chip for additional processors or memory. However looking at the space occupied by DRAM and GPU it looks like a larger die is required for any on board memory expansion.
