You’ll likely have to wait a while for these: end-user laptops / other devices using the new spec will only start appearing in 1-2 years (likely longer), once USB-PD controller designs are locked down and put into production, and third party charger manufacturers will likely only jump in after there are a couple of these devices are available.

Plus, the size / volume / weight / price will increase in line with the chargers’ output...

A similarly higher (split) output is coming sooner with the Omega 200W that pseudoswede mentioned earlier: Outfitting your travel kit for USB-C.
(Though, no idea / comment on expected reliability...)
