Should I wait until WP8.1 release or buy phone now?

Same question, as my phone is from Hong Kong and I'm in the Philippines. So, it's the same as saying even if the Black is released here, I won't get an update unless the same is released in Hong Kong?

No, just used and flash the STOCK ROM with your particular product code. Ex. RM-821 for my 920. You can download it anywhere you are.
