We can't say this was unexpected, but Sony just pinged us to say that that Nazi PS3 ad is "totally fake" and was made without their approval -- here's the statement from the executive president of BBDO Chile, which made the ads:
This creative design did not involve and was never approved by Sony Computer Entertainment or Sony. This "mock campaign" was developed by BBDO Chile staff and was submitted to various creative competitions/festivals without prior notification or approval from SCE/Sony, and it is not representative of the views or advertising policies of SCE/Sony. BBDO Chile apologizes for using this creative concept without authorization or prior approval, and for its misrepresentation of the PlayStation brand and its values.
Settles that, we suppose -- although we're guessing BBDO Chile isn't going to be Sony's agency of record very much longer.
