The leap in performance and power should be the same proportion as the leap from PS2 to PS3 was. The more the better. But there is currently to rush. The current gen still has a lot to offer for an other year or two.
People mention that they want 1080p and 60fps standards. That's great, but the problem is that most developers will neglect the frame rate in favor of more detailed graphics (more intricate shaders, more intricate lighting effects, better textures, etc...). Even if the consoles get more powerful, I'm sure we'll still find developers who will go that route again, to the detriment of frame rate. If you ask me, that's a moronic approach, but developers has been going that route forever now. Be it 30 or 60 fps, the beauty lies in the constant. So if you can't achieve a steady 60 fps, lock it lower at 30. ¬_¬
