Now that I think about it the movie characters are facing Weasley's in the movies often, with Olivandres on the left. So if you're facing Weasley's you're facing the entracne to Diagon. Malfloy is seen running off down an alley to Knocturn away from Olivanders which WOULD put Knocturn on the left side of the park. But all those pointed roofs and little passages on the right side of the new land definitely look a lot more like the Knocturn of the 6th movie... can someone with the knowledge please make a map...?
