PS3 and PSP connectivity has always been a priority to Sony, and it looks like they have some pretty exciting plans for the two platforms in future firmware updates.

One of those plans include having the PSP use some of the PS3's processing power. Says SCEJ's Matsui:

In future updates, there are thoughts of raising the level of interaction, in the sense of “interactive entertainment”.

Among those ideas are enabling the PSP to cope with more processing while using computational resources on the PS3 side for areas where the PSP lacks resources, so we think that interaction between the two systems will be possible by having them successfully complement each other .

Don't know how they can actually make practical use of this though, considering that the PSP is primarily a portable console. If you're stuck connected to the PS3 to use its processing power, it defeats the whole purpose of getting a handheld.

Matsui adds that future firmware updates of the PS3 will add more services. They won't necessarily be about gaming either, despite Kaz Hirai's strong words about video games being the PS3's main premise. Says Matsui:

In addition, as with Life with PlayStation, we take the approach of making the PS3 something people will use from when they wake up, like switching it on to watch the news in the morning.

Since we believe that there must still be many areas in with both the PS3 and PSP can be of use in people’s daily lives, we want to continue to make firmware updates with this perspective in mind.
