Microsoft's Peter Moore has confirmed that the Xbox 360 won't be cheaper this Christmas. And why is that? Moore explained in a yet to be published interview with game site SPOnG:

We're all feeling pretty comfortable with where we're at right now. I'm not sure why we'd change it. Sony gave us a price drop at E3. Obviously we don't talk about pricing [openly] and stuff happens but we have no plans to cut the price right now.

That means that Sony hasn't only made the new PlayStation more expensive, but also the 360! Regardless, I'm not believing Msoft's no-price-cut line until I see it tattooed on Peter Moore's bulging bicep. Brian Ashcraft
