Speculation like this is likely to drive the market up.  While it may seem good to be getting all this press, the negative attention from US senators and the labeling of bitcoins as a hacker's currency by the guardian makes bitcoins seem like something illegal.  The public doesn't understand the concept, and with the cryptography aspects it's likely to never understand it.  I think what we'll continue to see will be biased and uninformed reports, including fear mongering about the illicit drug trade, money laundering, and about a potential pyramid scheme.
