Battery life is an issue. The new iPad will have similar battery life to a PS Vita when playing graphically intensive games.
With a new iPad release each year, battery life can only go down. The iPad3 is already getting fatter instead of thinner. This is because this was necessary to maintain similar battery life to the iPad 2 despite the big increase in power.

The extra battery is more for the screen and 4G, and to a lesser extent the extra RAM.
