The change is only to the label. It will supposedly enhance the old school design, and I think they are adding a yellow hint to the ribbon from what I hear.
All I know is that the last time that they changed the look, people were pissed... then again, they changed the formula too.
And Pepsi really did have a label that when you put two cans on top of each other and then twisted them so that they lined up a certain way - it said SEX.
That, in my 10 year old brain (however old I was at the time), was an amazing thing.
