Despite the increased density/capacity being useless for gaming, I'm sure that won't stop gaming laptop owners from buying these sticks.
A number of years ago I had an Asus gaming laptop and spent a bit of time on the Asus ROG laptop forums. I swear every other thread was someone upgrading their RAM to max capacity (32GB total), replacing OEM SSDs with Samsung PROs (of the same capacity half the time), putting SSDs in RAID0, etc. All for only gaming/desktop use. Basically all the upgrades you can make that are useless outside of benchmarks/bragging rights. That wouldn't stop them from making vague, subjective claims of better performance though.
There are plenty of people in the PC enthusiast world that seem to have more money than sense, but laptop enthusiasts seem to take it to the next level.
