For complex historical reasons, I have a US PSN account and RB3 disc, but am now living and playing in the UK. My large DLC library is all from the US PSN, since DLC from UK PSN does not work with my game.

What I want to know is, do I need to get Blitz from the US PSN for it to export to my copy of RB3, or can I get it from UK PSN?

(The current exchange rate, not to mention the difficulty of even funding a US PSN account in the UK these days, makes me very much prefer to buy from UK PSN where possible).

Would very much appreciate an official response if possible!
