I have been thinking about the timings of the release dates.
The main piece of evidence is Watch_Dogs. It is coming out on November 19th on all current platforms and then out on launch for the PS4. This implies to me that the PS4 is coming out after then.
Not being American, I don't know when Thanksgiving weekend is....
The other main consideration is when the Xbone is coming out. I haven't decided if it is a good thing or a bad thing to have them coming out on the same day, but I doubt that one would like being a week behind the other. There will just be massive logistical issues if the come out the same day, or if they come out around Black Friday
I believe Microsoft have actually specified November, so I would guess they were both coming out around the week of the 25th.
