Why have mSATA or MiniPCIe on a 2018/2019 design? M.2 replaced both of those as of literally years ago, and anything remotely modern is only available in that format. mSATA is flat out dead and MiniPCIe has very few modern offerings.
It's not like there's a meaningful hardware difference, it's just a different slot pinout for the same technologies, but one's the modern standard and the others are outdated trash.
This should have two M.2 B-keyed and one M-keyed slot rather than the three legacy slots it has. And really, if I were in charge, it would have two M-keyed slots and only one B-keyed for WWAN. The SSD slot should be a M-keyed PCIe slot, not SATA nonsense. SATA is for spinning rust, PCIe NVMe is for SSDs.
SATA got eliminated for M.2 M-keyed (for NVMe SSD) in the redesign, see my other comment. mPCIe is still useful, because there are a lot of WiFi cards available in that formfactor that don't require firmware, for example.
