Again, I'd argue we still know a lot of these things for the Potter ride too.
Type of ride - coaster
Theme - Potter (no more/less detailed than "Mario Kart" or "Donkey Kong")
Possible layouts - we don't have this for Nintendo rides
Location - Dragon Challenge Plot
Artwork - Not a leak, at least not a leak in the final form. The final, actual artwork we have for Nintendo that represents the project as it will be built comes straight from Universal
