Well, I got used to hear people that they are going to choose another console or the PC this time around.I use my PS3 almost to exclusion this generation. It was mostly due to the fact that PS3 came with wifi built in when it dropped and I didnt feel like buying the 100 dollar wifi adapter for the xbox. Who ever thought up that price point for a wifi peripheral was a stone idiot.
From there i never really went back...
I can't say that I lean one way or another in any generation. I usually get most boxes in a generation.
Genesis and Super NES - preferred the Genesis
Saturn and PS1 - preferred the Saturn
Dreamcast, Xbox and Gamecube - they got equal love from me although i will say the Dreamcast was probably my favorite console ever. I still have my 9.9.99 shirt. Never got a PS2
Wii, 360 and PS3 - PS3 was my preferred box this generation mostly because of bluray and built in wifi.
This gen? I'm leaning Xbox One, not sure about the PS4. Wasnt really impressed by KZ footage (never mind that i cant play FPS'). Knack was cool but seemed a little bit LBP to me. *shrug*
As I have gotten older more of the features of the Xbox One appealed to me. They showed ME exactly why i would choose their box over just a games machine at the reveal.
I can tell you though that -policies aside- Microsoft is doing the right thing with the Xbox One, imho.
The Xbone is their first machine that despite its flaws -again, certain policies...- has some soul to it. I mean, the Xbox was very powerful but it was a generic machine compared to the PS2 and even the GC.
The Xbox 360 was so powerful for its time but again, it was quite rushed and evolved as time went on. The X360 of the early days has nothing to do with the X360 of today, save the hardware.
With the Xbox One they pulled a Sony, which are hardware specialists, and a Nintendo at the same time -going with a balanced machine- with a bit of Microsoft here and there -like the 3 SOs and the VM-.
In that sense I think that the console is going to surpass X360 sales with flying colours. Xbox reveal conference aside, things look very promising for the machine this time around.
