The Next Generation...Sooner or Later?

With new portable consoles launching this year and peripherals launched last year designed to lengthen the life span of our current home consoles, many speculate that we wont see new consoles for another 5 to 6 years. This means our current generation would've lasted 10 to 11 years. I feel its time for new consoles to launch within the next year to year and a half. How do you guys feel about this?
