Re: November 20th, 2013
I have to agree with emdeepee that a launch date for the end of this year woyld be very strange. October/November is typically the busiest period of the year for AAA releases and Sony aren't going to want to hamper those sales. Nor would any publishers want to release games for a console that's going to become old news in the same month.
Likewise, I'd be stunned if GTA V was announced as cross-platform. Sony will want a launch line-up of titles that will have PS4 snatched up. No-ones going to fork out on a next-gen console to play a game that'll run on their existing hardware.
I'd hazard a guess that we'll see another Q1 launch. It's the second busiest time of the year for big releases and I'd expect them to want most of those as launch titles. Maybe we'll finally see 'The Last Guardian'…
And I think Doc is right about the pricing. The price tag on PS3 hampered it on launch and they cut it as soon as possible.
