Motorola has just sent invites to the press for an event during MWC in Barcelona. The invite shows both Motorola and Lenovo logos and the iconic "Hellomoto" word. The invite says it will all happen on February 26th.
As you know, the only Motorola device that has been leaking in recent weeks is the Moto G5 Plus, and it even passed through the FCC recently. It's rumored to come with 4GB of RAM, a 5.5" 1080p screen and a new all-metal design similar to the Moto Z.
The FCC listing also revealed there will be other variants of this phone, one having 2GB of RAM, so it's very likely that the Moto G5 will come in Plus and Play variants like in 2016.
