I currently live in the United states and im going to move to the Philippines soon. i was wondering will i be able to bring my ps3 and play on the us servers or i cant ?, and if i buy a ps4 there will i be able to bring it back and play on US soil ?
Sure, you can coninue logging in on your account and access the same servers anywhere in the world. You can buy one there and bring it back and still use it but there might be an issue with dvds because of region locks etc. Also keep in mind that while games arent region locked and wont be on ps4, DLC still is so if you buy a game there, you will need to create another account for that region to purchase any DLC.
