When did Read announce he was stepping down? Oh, wait, he didn't.
Maybe because English isn't your native language you are missing the nuance of the whole thing.
I miss nothing, just that i m not doing hasardous speculations.
It was known apparently in the industry, such decisions are not rendered public before they are actualy acted.
In this case, my natural skepticism is dampened by a nugget I picked up at CES back in January. It wasn't anything I could report, but a well-placed industry source suggested to me that Dr. Su would very likely replace Read as AMD's CEO "within the next six months."
