Intel's Nova Lake platform will support up to 48 PCIe lanes.

That's 16 PCIe 5.0 lanes from the CPU for slots and 8 for storage, plus up to 12 PCIe 5.0 and 12 PCIe 4.0 lanes from the chipset. Given that even an RTX 5090 is barely slowed down by only having 4 lanes of PCIe 5.0 available, that's a pretty healthy number.

And 8 SATA ports and approximately 40 USB ports.

There are five different chipsets planned, though the W980 offers pretty much everything including support for ECC memory... Which is not a chipset function but a CPU one, but something Intel likes to do.
