Yes they will go on sale in the US eventually, but our release seems to always be behind whats released in Korea from Samsung. Its rumored to have a 11th intel cpu.
This gen, Korea's Galaxy Flex Book 15.6 had a nvidia mx250 gpu and 16gb of ram.
Our US version of the exact laptop got a intel iris plus gpu and only 12gb ram max.
If Samsung pulls that stunt again and gives the US a inferior laptop, customers need to pass.
Hope it helps.
