Searching through reddit, there seems to be some impressions from french journalists:
- All we've seen and played through demos until now is 1% of the map
- He then said that BOTW's map is about twice the size of Skyrim's world
- Zelda's world is filled with mini-dungeons, villages, life, and all sort of things. Doesn't feel - empty at all at any time, nothing like what we have seen in the gameplay. He complains that - the demo is the emptiest area in the game.
- Village types include villages of thieves, gentle farmers, etc
- The sounds are amazing and respond really to the environment and feels really immersive

he is relying discussion with a friend reviewer
some free translation on the go listening to him (sorry if not great English) :
- zelda on tv will look disappointing after horizon (ho really! ) but on switch screen it's holala to sum up.
- talk about size of map (1%, ~2x skyrim) and how huge it is. filled with a lot, a lot, a lot (he insists) village, pngs, dungeons , life and stuffs.(you get the feel a lot time as been spend on it). He insists what they showed was empty but it's in fact filled with lot of things to do, good and evils villages (lol) , hidden caverns ect...talks about horses outpost (sorry for translation here)
- this is based on three hour gameplay (exploration)
- he is personally not interesting in zelda or open world but he find it beautiful (understand colorfull)
- talks about gameplay and how it controls. how buttons are mapped etc ... and how it find this better than items map on button in old entries. he really likes that there is now a jump button and more control on how you use it in fight with dodge etc...
- talks about witcher 3 combat not being the big thing in it but don't want to speak about a game he haven't played.
- again talks about the map size (not as big as witcher 3)
- he is hyped by the switch
- performance report : no problem 30 fps (will need more feedback)
- talks about psvita and what it does to power it the first time (apparently switch screen does the same)
- says vita was 300 euros at release
seems about it for switch/zelda
