Something else to note, I didn't like xBox as you had to pay to play online vs. play online with just your internet connection with Play Station. That changes with the new systems where you will have to pay to play with the Playstation 4.
The other thing to note, xBox Live no longer has a family subscription. Family subscription was something like $99 (guestimate) and individual was cheaper but more expensive with multiple individual accounts. With the new xBox, they changed Live accounts to where all family accounts are now individual Gold accounts. A gold account is $60.
xBox One will be a single gold account for the single unit itself from what I've read. That means you, your spouse, your kids will all be able to be online with that single gold account. This won't be the case with the old tech xBox 360. I've read that each individual on an xBox 360 will need their own gold account. That would be 4 x $60 for everyone in a family of 4.
I only have an xBox 360 because it was given to me. Had I bought it myself, I would have definitely bought a PS3 for not having to pay to play online (I'm not online with the xBox.) With the new systems and Sony now charging for online, they are about equal and I think systemwise at least for the old systems, the xBox is a bit better than the PS3. Whether that carries over to the new ones or not I don't know, but I do like the xBox, just not the pay to play factor.
