Sony sees PlayStation 3 sales skyrocket 56%, Blu-ray a factor?

Despite the weakening economy, video game sales across the board have remained impressively high. Now that each of the big three have reported their Q3 figures, we found Sony's report in particular worthy of critique. Sure, Nintendo moved more Wiis last quarter than Sony did PS3s, and Microsoft sold about twice as many Xbox 360s, but that's beside the point. The most expensive console on the market (by far) still managed to see a 56% sales increase year-over-year, which is pretty remarkable in and of itself. We've no hard evidence suggesting that Blu-ray's victory in the format war helped escalate its sales, but would you be willing to bet that it did? C'mon, the PS3 was widely regarded as the best Blu-ray player in its price range for a solid while there, surely that helped out Sony somewhat -- no? Chime in with your analysis below.
