Considering how much havoc sovereign wreaked before he went down I really hope that by the end of this game you wont be shooting down reapers like they're some normal enemies. These things are supposed to be nigh indestructable and an unstoppable force, I'm really curious to see how they handled the story. This has potential to be the biggest letdown in videogame history, I'm literally praying that they'll be able to surprise us with the ending. Of course there will have to a way to stop them but it better be something unexpected and that makes sense at the same time. If they just pull a last minute miracle solution out of their asses or simply make us shoot at them till they go down, blood will be spilled.
I bet they find giant ring-shaped structures throughout space that destroy everything. Killing off the reapers but sacrificing all life in the galaxy.
