I never have thought thin laptops make a good gaming machine. Especially at higher tier hardware where thermals are really critical for a good experience. Besides the fact the hardware has become non-upgradable and who in their right mind would buy a used thin gaming laptop that has obviously been through some serious heat cycles. Nope not at the price Razer wants for these laptops, I would want some focus more on thermals and less on thin. If you want a thin laptop for travel buy something else for that.
This year, Razer uses a significantly slimmer case in the Blade 16, even though this requires compromises in some places. The new model looks a bit like a downgrade overall.
