Well, Dell, Lenovo and Asus are onboard, and at least Asus seems to be gearing up for some premium offerings. So far, these laptop chips were mid-level performers with mediocre battery life. At least in their marketing slides, they are potentially addressing both issues. Zen 2 on 7nm is allowing for high core count, higher clocks and low TDP. In theory they've also improved the idle states to reduce power usage under more conditions.

Both the above theoretical improvements and availability in desirable laptop chassis's will remain to be seen, but at least we can be optimistic, given the desktop wins we've seen this year.
