this particular incident may not lead to anyhting major but I think it could set a very interesting precedent for the future.
In THIS case the differences had to be nitpicked into existance, but WHAT IF there were blantant differences in the video quality between the PS3 and the 360 version and they showed the PS3 version trying to pass it off as the 360 video?
Advertisers might have to tread quite carefully from now on and ad budgets might have to go up, now needing distinct advert footage per platform the game is released on or at least disclaimers in the footage.
could be interesting to watch this develop - if it does that is.
