Typically, these high-end brands hail from developed countries. Only when there is enough of these rich and famous, does it make sense to have these brands and their corresponding marketing strategy.
Games, mass-market cars, consumer electronics, etc... do not usually fall under this category. These things are supposed to be sold to many people and the margin is not that great.
For example, Vertu is trying to be one of these brands... but their phone only has so-so features and most of us won't be impressed. However, they have a super concierge service that comes with owning the phone... and a price tag to match. It's a status symbol.
So, it is very natural that these brands usually come from the US, developed European countries and Japan.
You don't get these brands from less developed Europeans countries either... like Greece, Cyprus, Serbia, Czech, Slovak Republic, etc... So, naturally, you don't get such brands in most part of Asia.
I'm sure, given time, Singapore will start coming up with these brands... but it takes quite a lot of time. We have only just become a developed country a few years ago.
