Final Fantasy XIII - Freezing issues (warning)

Answer the poll to the right please.
I really didn't want to write anything about FFXIII until i progress further into the game, but as many of you know, there is so many people complaining about the game being laggy and that it freezes randomly, sometimes at the same spot with no hope of continuing the game.
unfortunately, i got the same problem too, i first noticed it when i was on chapter 6, the screen goes black when there is a transitions between scenes that occur, it happened twice, so i turned off the system, when i got back and played it again it played with no problems, that is until i reached the end of chapter 7, every time i beat the boss and i get the loading screen after the scene, it just freezes showing that is loading.
well, the problem might not be only the freezing issue, it's been noticed that after this problem, some other games freezes too, and faces some problems when they are played, and that also happened to me when i tried to turn on heavy rain, it just wouldn't work, so i left the system turned off to cool down (i wounder if it will run now, didn't try that yet). "Edit: it turns that one of the save file for heavy rain gone corrupted upon playing after facing the problem with FFXIII freezing, so it would be wise if you let the system cool off if you faced the freeze, and do not play or open any save file to be cautious."
to make it clear, i have an 80g fat ps3, the problem is happening also on 20g, 40g, 60g and some people who own the slim reported the same problem, also the X360 has it too, so i don't believe it's the system fault, it's mostly because of the game, beside, have anyone heard of any complaints about the JP version of the game???
anyhow, if you faced those freezing issues, be warned, don't play the game until there is some official statement about it comes out, i doubt that aether sony or Square Enix will just set with their hands up on the air while all those people are having those problems and sending their complains about it.
SO WHAT SHOULD YOU DO?
simple.. contact sony and Square Enix about the problem and let them know, if there is so many people complaining about this, then they should do something about it, or the trust we gave them will go away, and i don't think they want that to happen.
hope this problem get solved soon, i was really anticipating this game for years, and it might be the final "final fantasy" game that i would ever play, so i wished it would be a great closer for me to this series, if i was ever gonna stop playing the large platforms games.(i hope i don't stop thought).
