Microsoft and Nintendo can keep their charts and graphs, because Sony had the best presentation of them all with their Little Big Planet Level Press Conference Presentation.
Instead of having a boring power point presentation, they had the developers behind Little Big Planet create an entire level in the game that would show the current sales numbers for Sony as well as their projected numbers for the future.
I don't think I've ever seen such a creative use of a videogame. I actually didn't nod off during all these boring facts and numbers. Congratulations Sony! You rock.
