One thing to consider is that the PSP and PS3 have (probably) been such a large disappointment for Sony, and a large portion of Sony’s management staff that was responsible for these systems is no longer working at Sony, so Sony could move in another direction in the next generation than the one people are used to.
One thing that could (potentially) be very bad for Sony is they could try to copy Nintendo’s success with the Wii without understanding why the Wii was successful. Now, I don’t want to speculate on what they would try to do but Sony has demonstrated a lack of understanding on why people like a lot of things when they try to emulate them. A fairly recent example of this is Playstation Home because, while it is an improvement in many ways over anything that has come before it, it doesn’t offer the functionality that Second Life or World of Warcraft do that make them so popular as virtual spaces.
