I'm not entirely sure, but I think the rule of thumb is that the character sheets will never be downloadable before the street date of the product. For the Magus CD, that's 5.9.17 according to Amazon, so I wouldn't expect the sheets earlier than that.
(That's actually an advantage of living in europe, since the CD will arrive around the street date with standard shipping anyway.)
That being said, I'd like to know as well - same for Reepazo.
Why go by Amazon when paizo has it available now...
Checking amazon is faster than searching for the street day on the paizo forums. I'm not telling you to buy it at amazon, I wanted the street date to estimate the arrival of the character sheets.
Going back to the actual topic, the answer is "They haven't given us one." I'd add that updates in general have been a bit slow lately and will definitely be slow while recovering from Gen Con.
Aside: The Magus deck's release date (according to the discussion thread from the Magus Deck page) was the 17th, at the start of Gen Con.
I got an email that the card game character package had been updated. That is the package with the artwork of the characters. It isn't the same as the character sheets. By chance you mix up the two products, which have similar names? Where did the link in the email take you?
