It looks like Ash may have been right. Stuff magazine is running a rumor item on the possibility of an upcoming Aibo, the robotic dog, working with the Playstation Portable and Playstation 3. The rumor goes that the Sony Aibo PS, as they call it, is being resuscitated by Sony's Playstation division in an attempt to "bolster the PS3's arsenal."
The Aibo PS will appear with its own avatar within Home and react in the real world as he does in the PS3's upcoming interactive environment, according to the article. The rumor article goes on to say that you will be able to download new personalities for the dog from the Playstation Network and that the dog will be fully controllable using a PSP via WiFi. The dog's head camera will send a real world vid feed to the PSP's screen as well. The Dpad will control walking movement and the four main buttons will deal with head movement, which seems odd.
