Speculations for Mass Effect 4?

I am curious what you all think about the teased Mass Effect 4 title. Who will we play as? Who is going to be the new Big Bad? What time will the game take place In? What do you guys want to see in the game?

Personally, I’m pretty sure that they’re going to have us take control of a new protagonist. I hope they don’t do something stupid like Shepard’s child. I would like to see a new character that is well done. I heard rumors that it’s going to be the Geth as the Big Bad again. I also hope that is not the case. I feel like it would just overturn everything that took place in ME3. Since we know that Liara is still alive since we saw her in the trailer, and no other crewmates. I can see with a certain level of certainty, that the game will take place a few hundred years in the future. Especially since they are trying to tie andromeda into it as well. I hated Andromeda, so the less that game touches ME4 the better.
