What are the Creality V4.2.2 and 4.2.7 boards? | Live Stream | TMC? 4988?

Creality has released some new boards without much fanfare. It's confusing users so we're going to try to get to the bottom of it.

Recap:
There are V4.2.2 with TMC2208 and HR4988 (A4988 clones)
The V4.2.7 appears to only be shipping with TMC2225 (Basically 2208s)
