What worries me about BV, is that they would be sooooo easy to superfake; particularly in Italy.
Most of them have so few truly distinguishing features, that all you would have to do is get the leather, the construction and the interior heat stamp right and the rest looks like relative child's play, to me... :s
Other brands have elaborate hardware, all over the place, often stamped or engraved with logos and yet, they sell for the same, or often less, than BV, so it is very hard for the fakers to get everything right and may even not be cost-effective for them to really try hard to do so.
Whereas, BVs are so expensive these days and yet so simple, that it makes it well worth the high-end fakers' time to get the few details they have absolutely perfect.
As their popularity increases, I think BV will need to work hard to produce, hidden, distinguishing features.
