I wouldn't be surprised if the ps4 is only a small jump in terms of processing power over the ps3. I expect Sony to take a more GC to Wii style upgrade and focus more on changing how people interact with the game or some other form of point of difference.
If Sony is a loss leader with their hardware next gen then they're idiots. I think the most important lesson of this gen is that hardware should be sold at a profit from as early as possible.
