From what I can see from the layout, BCV will have about 45% of its rooms with some kind of view of Epcot. and the rest facing away from Epcot. It will thus have more rooms than BWV that can see Epcot. The view should be better from BCV but it will simply depend on what ends up being between the rooms and Epcot (trees, structures, etc.). What you can see from the BWV rooms that are on the boardwalk is Spaceship Earth and the Illuminations fireworks. Most BWV rooms face in the other direction toward S/D and MGM.
