For the past three years AMD has held an annual Financial Analyst Day at its HQ in Sunnyvale, CA in November. That was the case for 2008, 2009 and 2010. There hasn't been a Financial Analyst Day in 2011 and based on AMD's most recent announcement, it looks like there won't be one until February 2, 2012.

AMD's Financial Analyst Days are usually where AMD discloses its long term roadmaps for future products. It's where we first heard about Phenom II, Llano and Trinity. AMD just recently got a new CEO, which helps explain the delay to February. With a new CEO potentially comes new corporate direction and perhaps a new roadmap.

That being said, I wouldn't be too surprised to see a CPU core roadmap update before the end of the year.
