The the M1 is Zen3 5600X performance in an ultra-portable form factor. Whether that's revolutionary or not particularly noteworthy depends on the individual use case. If you're don't care that much about power/heat/fan-noise, it's neat but not (yet) world shattering. Bit if you live your life on a small laptop, it may well be.
According to rumors, we'll see Apple's 8 Firestorm + 4 Icestorm CPU within a quarter or two in the 16-inch MacBook (current M1 is 4 Firestorm + 4 Icestorm, where Firestorm is the high-performance core). That will perform somewhere between a 5800X and 5900X (or some recent 16-core Xeon that nobody remembers the name/number of). Again, revolutionary or meh depends on use case.
Linux native is not in the cards but it won't matter, it will work fine virtualized with hardly any performance penalty (for ARM64 linux). If for some reason you insist on native linux, it's time to recognize that Apple hardware is not for you.
Personally I run my server workload on servers far away and let other people deal with infra (particularly, power, networking and physical security). But it's probably great for heavy media creators on the go.
