This is mostly due to the Wii. We can also blame Microsoft for not cutting the price on Xbox 360 in years. The only thing the PS3 is guilty of, is old age. It's natural for sales to slow down over time, Nintendo responded with Wii U, Microsoft doesn't care, Sony is trying with Super Slim.

I don't think Microsoft would release the next Xbox and do a huge price cut on 360....most likely they will be making a loss with each new Xbox sold, so the Xbox 360 is what will keep them gaining profit.
