Apple
wont mimic the design of the new iPhone 4 seeing as they want to make a firm line between iPod's and iPhone's. Only small upgrades in design will be likely seen.
For the features, however, i wouldn't be at all surprised if Apple
added a 3.2mp camera. If any camera is going to be added, it would be on the back over the front. A 5mp wont come in this generations iPod Touch seeing as Apple
want more sells on the iPhone rather all eyes on the new iPod Touch.
It may get a Retina display, but thats unlikely due to the fact that they dont want iPod Touch's to become identical to iPhone 4.
FaceTime could be likely as in Apple's
earlier Press Conference, they did mention that Apple's future products should come standard with FaceTime to promote such an App/Product. However, if FaceTime is included in this generations iPod Touch, then that will lead to a Front-Facing camera, which may not be plausible.
The Processor and battery-life will proberly increase in performance too, judging if Apple
want to create more sales in the iPod Section...
Well thats my assumption on the upcoming iPod Touch 4G
