I for one would be curious to hear what his source says now. Might just be that the source predicted announcement within a certain window, and also assumed it would be on a monday, and so said by today since it was the last monday within the window.
Maybe the source admits he f-ed up, or tells a plausible story about slight delay. Whatever, it would be interesting to hear.
If something happens tomorrow or wed. I'm inclined to say it confirms silverback's credibility.
Anybody who really expected an exact date prediction to come out dead on deserves whatever they get (e.g. some worthless feb. out of the money options).
