While the changes put them more in line with the competition, I'm still siding with the PS4. Even if they were the same machine with the same games, Sony's attitude and the way they presented themselves during E3 and the reveal got me on their side. Seeing the likes of Mark Cerny, Johnathon Blow, Greg Kasavin, Adam Boyes and a wealth of other recognisable faces who seemed passionate about what they were doing spoke to me as a long time gamer. When MS did it, I just saw a bunch of business people. Mine Craft is no longer an indie darling when it's sold over 20 million at this point and while it's nice of you to show Capy's new game and you wear a t-shirt, it speaks louder volumes if you actually got them up on stage with a few others like Sony did.
It still doesn't change the fact that the One is £80 more expensive than the PS4, doesn't support F2P in the same capacity, it's exclusive games don't interest me in the same way Sony's do especially in the case of Naughty Dog and their stance on indie games got worse and worse as time went on with the 360 and seems no different on the One.
At the end of the day though, it will actually come down to using these consoles. The PS3 won me over in the end due to PS+ and playing games such as Uncharted and inFamous whereas the more and more MS updates the 360, the more it pissed me off but the PS3 has massive quirks that are really hard to ignore such as no background downloading, poor controller, deleting shit is weirdly confusing and inconvenient, downloads take forever and their UI is inconsistent as fuck.
