A couple of B2B sites have started listing Lenovo laptops that feature the upcoming Intel 'Whiskey Lake-U' CPUs. The notebooks include the Lenovo s730 and IdeaPad 730S powered by the Intel Core i5-8265U and the Lenovo Yoga 730 powered by the Intel Core i7-8565U. Not much information is available about these notebooks right now but we can expect them to be officially announced during IFA 2018.
