I mean, it's pretty obvious Nintendo's retaining their floor space because of booking requirements and not because they really thought Zelda needed all of it, but as long as their confidence in it is justified they shouldn't have too much trouble using that space with just Zelda.
These convention spaces tend to be pretty disgustingly crowded, with lines often getting snaked around in stupid ways and even getting capped/cut because of fire codes. No one's going to complain about having a little room to breathe while they're playing.
