What I'm surprised about is that people are just realizing that retina uses a lot more processing power. I bet most people still don't realize that a "retina-optimized" game should should have half the performance on iPad 3 compared to the "low-res" version on iPad 2, if everything else is equal, even though the GPU in iPad 3 is twice as strong.
Yeah, twice as strong but pushing four times the pixels, I think a lot of people get easily confused. What can you do but hope the hardware improves more I guess.
