In an official Press Release at the Japanese Playstation website, Sony has announced that PSP firmware version 2.70 will be available tomorrow (April 25th) in Japan. There is no word on a release in the US at this time.
The official update page has the details on what is being added with this new firmware.
* “Internet Browser” now supports the playback of Macromedia Flash contents. *To play these contents, the feature must be activated in the PSP “System Settings.” *Macromedia Flash Player 6 is featured.

As you can see, the big addition this time around is the Macromedia Flash Player. It appears to be a pretty decent update this time around and not just some security patch as some of them turn out to be.
Again, there is no word on a US release date for this firmware but rest assured, it is coming.
