The 2017 15.6-inch Legion Y520 will split into two successors this year as the Legion Y530 and Legion Y7000. The Y7000 represents a more natural evolution of the existing Legion design while the Y530 will be more restrained in its looks to appeal to office workers. Both, however, are otherwise very similar in performance and internal options.
