At least that's what they claim. If you visit the Opera Freedom teaser page you are greeted with an image of a cloud that is split in half by a lightning bolt and the text "15 years of browser innovation. On June 16th at 9:00 a.m (CEDT), we will reinvent the Web". While that is not lots of information about the product or service that the Opera team is announcing it is definitely a bold statement.
If you look at the source code of the web page you get two additional hints. The first is located in the metatags which reads "The Web is your browser. Discover how fast and fun the Web can be" while the second is located as a comment in the html "We start our little story with the invention of the modern day computer. Over the years, the computers grew in numbers, and the next natural step in the evolution was ...".
Taken those two hints into account it is pretty safe to say that Opera will reveal a web browser in the cloud. It is not entirely clear how users are going to access that web browser, could be by using some sort of launcher that the Opera team is providing. Could also be a hybrid web browser that is being launched locally but gets most of its data online.
I could be completely off though but the cloud image seems to hint at this direction as well. Anyone got another interpretation for what Opera is going to announce on June 16?
