@sooty: Still, I'd rather wait to see if anything pops up. More important though, no system ever has enough launch games that interest me and justify the price tag. I'd rather wait until a decent library develops. As a side of bonus of that waiting, hardware revisions usually come up and the price drops.
There are no official launch dates yet, but the rumor mills are saying we won't be getting the PS4 in Europe until January 2014, so, no, not this year. But I'm strongly considering buying the PS4 once it's available.
The last time I was an early adopter would be buying an Xbox around the 7 month mark of its' initial release. Didn't buy a 360 until Street Fighter IV came out in '09. I might buy the new Microsoft Box week one if the system specs impress me enough.
