Yeah I've heard all that too. It's hardly an outright 'no PS4 for Europe in 2013' though, but I take you point. To be honest, I'm just trying to be optimistic, until I hear a definitive yay or nay.
In their announcement they stayed a holiday 2013 release for America and when questioned re Europe they wouldn't commit to the same American date due to complexity of global launch etc.
Now holiday 2013 means xmas so likelihood is November or early December release in America and I would eat my foot if Sony shipped it in Europe in the same time frame.
