>(Surely, the tough 8 GB RAM decision was influenced by the three factors 1. current DRAM cost and 2. limited DRAM availability considerations as of 2026, and 3. the massive Neo market size resulting from its attractive price tag, and this may get reconsidered in future editions.)

Actually it's because the A18 Pro only supports 8GB of RAM. It's packaged on top of the SoC itself using TSMC's InFO-PoP.
