Next Gen Consoles will Probably Arrive Later than Usual

I think this E3 prooved that the next gen consoles won't come out until a bit later than the usual 5 year cycle.   By now we would have seen new information about it.

And this has me at two points.  Unlike just about everyone else it seems, I want a new console. If I just have to pay $400 for a new console, it really isn't bad at all.  With that would come better graphics and whatnot.
That being said, I've also noticed something else--> consoles are seeming to be able to start hitting a stride they weren't before with no sign of true end.  It's well known that besides the launch of a console, there's typically no great new games for about a year.  And really, it seems like there's tons of life in these consoles. 

So what do you think about it?

Hasn't this been pretty much known for a long time? I mean ok, this E3 may have solidified it but have people really still been thinking that they were going to be releasing another console fairly soon?
