Well, for one thing, it might still be. The forced perspective on most renderings makes them look like glass shards jutting out from the ground, when in reality, they're boxes. (B/A, anyone?) And then there's the impossibly luminescent magic cladding that rendering-makers love to put on their offerings, and the impossibly healthy magic trees (behold, the mighty Renderwood!) that line the sidewalks. What we'll get, of course, is a matte glass box with a bunch of scraggly Charlie Brown Christmas trees out front.
Murano can't possibly live up to its rendering. So if Burano wants to take a more understated approach to their rendering, then I for one am all for it.
