Lots of m4 options are available now. The difference is really going to come down to power mode and/or peripheral function differentiation. Additionally, the support for higher level functions to easy peripheral programming and firmware IP for functions like motor control will make a big difference. Lets see more about these topics in similar product announcements going forward.
For a part that samples soon, this has very little real information.
I did find this : ["The XMC4000 series has a cpu subsystem, dsp functionality, a floating point unit, a fast flash memory with 22ns read time and error correction code, large sram and extended peripheral functions. These include new timer modules; up to four parallel 12bit a/d converters with a sampling rate of 70ns and a conversion time of 500ns; up to two 12bit d/a converters, up to four high resolution PWM channels (150ps); and integrated delta-sigma demodulator modules and touch button modules. "]
and in their FAQ they claim this is NOT Automotive applications. (yet have multiple CAN bus?)
No prices, apart from a cryptic 1e to 7e indicator.
I wonder what 1e gets you ?
Google helped find a more complete chip-analysis here (needs translate)
and a road map here - just Google :
Hints that 1e@10k claim could be ?
