In a MS powerpoint by AMD it could have had a slide with
"8GB GDDR5, an excellent choice for AMD APU's" and then go like:
"Whoops, that was supposed to go in the powerpoint for the other guys" *wink wink*
Some people are always claiming that a dominating console platform is bad for competition and the industry, so AMD could have singlehandedly changed the console industry, for the better (according to some, if you extrapolate their reasoning).
Or in the elevator, the AMD boss says to Don Matrick after a meeting:
"Do you trade stocks Don? No? Well, you should. I hear the company 8GB GDDR5 is about to go through the roof" *wink wink*
Or after the meeting the AMD boss goes to dinner with Don Matrick, they have a great time, the food is excellent. Don says: "We should do this more often!" The AMD boss says, yes, our glasses are empty btw, let me order some more:
"Waiter, could we have another bottle of 8GB GDDR5 over here? Oh excuse me Don, I always sound like Sony when I'm drunk" *wink wink*
the possibilities are endless as you see. No need for backstabbing secret documents leaking out-type of deals. Just a patriotic meeting between 2 bosses who want do whats right for the industry
