Regarding the theory about the basement containing some superweapon built (or owned) by Grisha which can only be activated by the Coordinate, I think it's highly unlikely to be the case.

This is because there is still one big unsolved question about Grisha's actions. After he ate Frieda Reiss, Grisha Yeager became the one and only wielder of the Coordinate. Even without activating the Coordinate's power, he could have easily transformed into his Titan form, headed to Shiganshina, cleared out all the Titans in the vicinity of the basement, and activated the superweapon himself. Why didn't he do that?

Why did Grisha instead, by sacrificing his own life and invaluable knowledge of the outside world, hand the Coordinate to his son? Eren Yeager, who has no special traits (unlike for example Historia who has the Reiss bloodline). Eren Yeager, who had no idea on how to control this power, much less know the truth behind it. Eren Yeager, who given his recklessness could have been killed on multiple occasions. Why did Grisha take such an enormous risk with the fate of humanity hanging in the balance?

There are so many doubts, but one thing is for certain. Grisha didn't do what he did in the hopes that his son would reach the basement only to get to a "PRESS THIS TO SAVE HUMANITY" button waiting for him. Grisha would have used it ages ago if that was the case.
