PSP-3000 model revealed in official Sony documents?

An Internet-sleuthing PSP fanboy has found evidence of a possible upcoming revision to the PSP, however we don’t know much about Sony’s plans to update their handheld hardware at the current time. In fact, there is some speculation that the “discovery” of the PSP 3000 label in an online user manual represents nothing more than a miscommunication between Sony and a third-party web developer. So far, the only scrap of evidence, is a tiny GIF image found buried within Sony’s online technical documentation. Nevertheless, the potential existence - no matter how unlikely - of a new PSP revision, has us quite intrigued.

We have already outlined some of our own ideas about improvements we would like to see in a future PSP model, but we are curious to hear what our readers think. Is it too soon to consider yet another PSP revision?
