And I completely agree with your second point and it is my point exactly. VARIATIONS ON A THEME was my argument all along. I never said anything about carbon copies.
My issue is that there is so little deviation between Casa I & II, that if the third one is substantial similar, then we won't really be getting variations of a theme, but rather carbon copies. The only substantial difference between Casa I & II is height and the gold crown on the latter. I'd much prefer a Casa/Theatre Park/Charlie combo than a Casa/Casa/Casa combo.
