Almost every single ICO has made the claim that they are not securities and thus do not need to be regulated by the SEC. The SEC has not provided any insight beyond their analysis of the DAO token. The DAO was a decentralized investment firm, and pretty clearly a security. While it may have come as a surprise that the SEC was investigating the DAO, I don't think anyone was honestly surprised by their findings. So, there's no official answer to your question. No other ICOs have been deemed a security or not a security - only time will tell what happens next.
