I think we have to just wait and watch, what Lenovo is going to do with Motorola.
Following three good things may happen
 Motorola phones getting SD slots again like all Lenovo phones.
 Motorola phones to come with bigger batteries NOT JUST IN DROID MAXX series like earlier, as Lenovo phones also have bigger batteries [P780 has 4000mAh battery)
 Motorola phones to reach much more markets especially in Asia and Europe.
 More better and affordable DualSIM phones (again NOT for USA) for Asia, Europe and Brazil
But following things are in UN-SURE mode
 Moto's faster updates MAY NOT continue (esp after Lenovo becomes boss of Motorola) as Lenovo has bad update history (if one exists in first place)
 Unlock BL program may NOT continue esp for GSM handsets sold in Asia and Europe, as I don't think Lenovo cares about Dev support
