Good news for anyone who owns a PSP and may be purchasing a PS3. Sony is currently demonstrating several of the Playstation 3's features at CEATEC JAPAN 2006, a consumer electronics convention currently taking place in Japan.
Sony has been demoing the Playstation 3's "Cross Media Bar" interface, which if you own a PSP, you're already familiar with.
During the demonstration, Sony showed an icon under the Playstation 3's "Network" menu called "Remote Play." As you can see in the image below, it clearly depicts a PSP.
Sony has also confirmed that you will be able to use the PS3's integrated WiFi functionality to "throw" the PS3's video signal to your PSP. Details were found in Game Watch's coverage of the event. So not only will you be able to use your PSP to control your PS3 games, you'll be able to use your PSP to see your PS3 games.
It should be noted that because only the 60GB Playstation 3 model includes integrated WiFi, this function will apparently not be available on the 20GB model.
This feature may just be one small component of Sony's implementation of
DLNA on the Playstation 3. Other possible (as in, we're just guessing) implementations include being able to watch movies from the PS3's Blu-ray/hard drive on the PSP, and being able to watch UMD-Video on the PS3.
Update 1: We may have spoke too soon -- Famitsu's coverage of the same event presents a different story. They say that "Remote Play" will be used to, and I quote, "download Playstation 3 content to the PSP." That's a bit different from Game Watch's take, so I suppose we'll have to wait and see.
