Others have clarified this but to add mainstream RZL notebook series(RZL-H, RZL-M....) plans have been gone for some time apparently. RZL is primarily Desktop only with -HX series for laptops and possibly RZL-AX(Halo). Then there's RZL-WS tentatively for "HEDT type" platform.
This is what it looked like to me back then when I wasn't sure if TTL would necessarily incur a delayed cadence and/or possible core-changes. TTL very likely will have LPDDR6 support. For sure lot of things can get changed or cancelled.
