NAND bandwidth is mostly limited by how it is connected (i.e. SATA or PCIe3) not the individual NAND devices themselves. PCIe3 x4 has a max speed of 4 GB/sec, which after overhead is less which is where you see today's max of around 3500 MB/sec. Now imagine Sony is using PCIe4 x4 - that's 8 GB/sec which after overhead is less but still twice what any PC SSD is capable of. You might need wider paths between controller and NAND, but it is an embedded device so you don't need a socket or slot to plug a physical SSD into - it will be soldered onto the board. The controller and NAND may be stacked so any greater data path width is hidden inside TSMC's packaging.

I don't know why you are looking for esoteric solutions when the fact it is an embedded system and PCIe4 will be available when reaches the market easily account for Sony's hyberbolic claim.
