Dont get the problem with this statement? As a long time PS3 owner, i only got my 360 this year and thats directly because of the great bundles that MS have made available as well as the more affordable price.
Now sony is catching on and doing the same, by releasing great bundles at round about the same price. OBVIOUSLY these deals are enticing to gamers who only have one console! He is just stating the obvious.
People forget that at the end of the day a gamer is a gamer. And when a 360 only owner watches some awesome uncharted trailer or the last of us trailer, it makes them want to go buy a ps3(provided the price is right ofcourse ^^). Its that simple.
