It seems as though a lot of people in the comments don't know anything about this reboot.
There will still be research...which is even alluded to in this trailer. You will use radio and radar to track aliens and conduct field investigations. Basically, they understand the roots of the franchise and are trying to incorporate some of the things that made the original what it was.
So calm down, educate yourself, and realize this game is close to a year away.
