Following the earlier news on July’s NPD sales data for the US videogame industry, SCEA’s analyst relations manager Mariam Sughayer predicts that September is going to be a big month for Sony.

Sony sold 159,000 PS3 units in North America during July, which is a considerable improvement on the 98,500 sold in June and 81,600 in May. Why the sudden increase in consumer interest?

“From a PlayStation perspective, coming out of E3 we were really anticipating a good reaction to our new hardware pricing announced on July 9th, and we were obviously very pleased to see that PS3 sales increased with 159K units sold at retail for the month of July, which puts us up 61% over June numbers,” Sughayer writes on the PlayStation blog.

“While I think a lot of that had to do with the new price, I also think there is a great deal of anticipation for the line up of games just around the corner, including Warhawk (Aug. 28), Lair (Sept. 4) and Heavenly Sword (Sept. 12). In fact, September should definitely be a big month for us when you add in the launch of the new, slimmer, lighter PSP (pictured) which will hit store shelves next month.”
