It's a risk, but like everything else it depends on how much risk you're willing to take.

If you wait for the local set to launch...
1. It may take two or three months
2. the 32gb version may not be available
3. the price will be steeper (maybe RM1900 for the 32gb if they have it?)
4. Local warranty

If you can get it from the US/Australia...
1. You get it earlier
2. The price is much cheaper (about RM1300+ if you can get a friend to bring it back, if not RM1500-1700 from sellers here)
3. Overseas warranty so it's troublesome
