Where's the final battle going to take place in Book 7

I think it's going to end at Hogwarts. It's the one place both Harry and Tom felt at home. I think the battle will take place on the grounds or in the Great Hall. Tom will have the Giants on his side, the Slytherin students might join him to, Harry will have the Gryffindors Hufflepuffs and Ravenclaw students. Charlie might bring dragons with him. The DA and the Order will be behind as well.
