Eetimes reports that Lenovo is getting a team of 100 chip designers together (60 in Shenzhen, 40 in Beijing) to design and integrate their own ARM Processor designs.
Because Samsung may not agree to provide them with the latest fastest Exynos designs and because Lenovo needs own differentiation in this market.
I expect Lenovo to use ARM in ThinkPad Laptops soon also, using Chrome OS in priority.
