there will be a retina display. gyro and the face time dual cams for the true 4g. the gyro is for gaming. the cams are needed unless apple plans on lying about the tens of millions of facetime devices. the retina for compatibility with the newer high res apps. the A4 processor will be there as well. chances are, it will look like a mini iPad. with the anodized aluminum back. the A4 processor will be needed to power all those new games and the higher res screen. Apple might also use the better glass on this year's ipod. if they change the design, then they will have all models be 4g across the board. maybe a price increase to 229 so the profit margin is better on the low end 4g. the only reason that apple was able to get away with the fake low end 3g last year was due to the fact they looked identical. where is a time machine when you need one!!!
