As per http://www.androidpolice.com/2016/01/07/lenovo-will-retire-the-motorola-brand-in-favor-of-just-moto/ it appears that Lenovo are going to ditch the Motorola brand in favour of a Moto by Lenovo brand. Batwing logo still to be used.
The first two phones I owned were Motorola phones. I was pretty annoyed when Google sold to Lenovo but not so annoyed now. Shame the brand has ended though.
