HiFive Pro P550 by SiFive and Intel being released this month - high performance RISC-V SoC

SiFive has a page up now saying that this new HiFive Pro P550 SoC will be released this month: https://www.sifive.com/boards/hifive-pro-p550

I'm assuming that since Intel is involved that there will be proprietary bits and maybe an ME. The specs look interesting, with up to 16GB DDR5-5600 memory. The chip will be a "SiFive Performance P550 Core Complex, a quad-core application processor featuring a thirteen-stage, triple-issue, out-of-order pipeline with the RISC-V RV64GBC ISA" - whatever that means. Sounds speedy and powerful with all those cool marketing terms.

It will probably be expensive. It will have integrated graphics and won't come with a wifi card by default, so it's possible that it won't be too horrible to run from a freedom perspective.

Just thought I would throw this topic up, see if anyone had any thoughts or has heard more about it.
