June 9 will be an auspicious day for two companies. Well, a company and a half. It is the start of Lenovo's Tech World conference and, naturally, Motorola will be there, too. While Lenovo itself will have a few mobile devices to show off, Motorola has its own thing as well. Tomorrow, we'll finally get to see if the Moto Z, or maybe just the Moto X4, can really bring Motorola back to the top the way the RAZR did nearly a decade ago.
