Which stage is Semis suppose to be played in?

I heard Semis and Grand finals will be played on a different stage than the one used in Group Stage. But it looks the same.
So Which stage is it?

Let's wait....we will see

Its different stage, but they use same elements so it looks similar. I'm pretty sure
