Sony already have there own cloud service - Gaikai
Sir, you are comparing two different cloud. I'm talking about the good cloud, the cloud that enhances you and your games. Seriously.
Yes, lets join the MS propaganda party. MS and Respawn made up a bullshit lie that Titan Fall was exclusive because of Microsofts cloud features, yet the question remains as to why the 360 has it if that is the case. We all know MS moneyhatted them a long time ago before Titan Fall was ever announced. Sonys cloud features can already accomplish what Gaikai was doing and if the 360 is getting the game theres no reason the PS4 shouldn't.
I would do the same thing If I was offered some free cloud too. They had no choice, Sony's cloud is smaller and shorter.
