360 was killed in sales worldwide by the PS3 before last september price cut, and I doubt it will be different when Sony cuts the price (probably in August).
As raf pointed out, the main reason why the 360 is doing better this year is its price : it's half the PS3 price, but doesn't manage to sell better than the PS3 right now worldwide, so it's hardly a great success for MS.
