Do you know what house/flat you'll be moving into? Flats and houses here tend to be tighter quarters than in the US.
In our old rented flat and in FIL's house, I don't think there'd be room for two TVs and multiple gaming consoles. Even in the bedrooms, there's just not space suited for a TV.
Obviously, if you really want them and can't live without them, you can find a way to make it work, but be prepared for the possibility of a tight squeeze.
