Sombra is old news now, and the Overwatch community has found another thing to speculate about -- Doomfist.
Doomfist is a name that can be found in many different Overwatch trailers and portions of the game including the first Overwatch trailer.
In Numbani, Doomfist posters are scattered about, and the Payload on that level has Doomfist's glove in it. He's clearly from Numbani, and Terry Crews clearly wants to voice him.
I can picture the marketing and commercials now. High-octane action of Overwatch gameplay coupled with Terry Crews shouting about how great it is to be Doomfist.
If Blizzard is smart (which they absolutely are) they would take Terry Crews up on his offer and have him voice the latest interest of the Overwatch community.
