You shouldn't look forward to a battle that you're going to lose, no matter how badly you lost the last one.
The Master Chief Collection and Sunset Overdrive will not outsell LittleBigPlanet 3 and Drive Club by a very wide margin, therefore exclusive content will not make a major difference. Additionally, the PS4 has all of the momentum as well as superior multiplatform titles so the best Microsoft can hope for is to sell enough hardware to at least remain relevant in 2015.
