Well, there was a Sony Service Centre in Malaysia all this while anyway. It isn't a BIG transition for them to fix PS3's..

I believe the Microsoft service centre in malaysia is only software support? Officially launching x360 in Malaysia would be a big capital cost relative to Sony.

To answer your question. Not likely anytime soon, if there is any chance at all. It is simply not commercially viable.

I Believe launching Zune or computer accs in malaysia would be their first step rather than the x360
