Sony has examined the most recent NPD numbers and, happy with what they saw, are attributing their 61% jump from the previous month’s numbers to the PlayStation 3 price drop they announced just prior to E3. They are quick to point out that anticipation for some actual exclusive titles like Heavenly Sword  and Warhawk may have helped drive interest in their slow-out-of-the-gate console.

Despite the predictably upbeat tone of Sony’s blog post, some have had a less than enthusiastic response to July’s NPD numbers since many analysts predicted that Sony was going to beat the Xbox 360‘s sales in July largely because of the price drop. That the PS3 was still unable to overtake the 360 in sales in spite of a comparatively more affordable price has some worrying that Sony just doesn’t have enough market draw to convince consumers to take the plunge. What is plainly obvious now is that Sony drastically overestimated the price the market would bear: It’s wallet-busting PS3 has lagged in sales from the beginning while Nintendo’s $250 Wii has flown off store shelves consistently for almost a year and as soon as the price went down on the PlayStation, it saw an improvement in units moved.
