He sounds like a politician trying to spin things to look more extreme than they are.
The market has grown substantially and now touches customers it never did before. It's pretty much a no-brainer that market share would sift in that situation. It certainly doesn't mean the previous segment of the market has been replaced or "killed".
Also, with that massive growth in the number of customers, an increase of .5 billion in revenue seems awfully tiny. It leaves the impression that this new market segment spends very little per customer. I'd love to see a breakdown of that.
Finally, this doesn't mean a whole lot to me right now, since he's using the last years of a generation, and the first year of a lackluster launch, as the basis for his conclusion. Let's see how much revenue handheld consoles account for in 2012, and if the Vita does improve it's numbers, 2013. THEN he can tell me that he has killed that market.
