I guess all the popular targets have already been hit, so the rumour is that Anonymous is going to be going after companies working in the oilsands:
In related news, Anonymous said it planned to attack oil firms and banks supporting the controversial extraction of oil from sand in Alberta, Canada. Exxon Mobil, ConocoPhillips, Canadian Oil Sands, Imperial Oil, and the Royal Bank of Scotland have been put on notice that they are likely to be targeted in Anonymous’ latest operation, dubbed Project Tarmageddon.
Anonymous began with attacks on the Church of Scientology in early 2008 before it made headline news last year with attacks on financial service firms that blocked donation to WikiLeaks following the release of controversial US diplomatic cables. Another long-running campaign has targeted entertainment industry firms that hassled file sharers or console modders, most notably Sony.
