A new iPod Touch is inevitable, and the rumors will keep pouring in until something is confirmed. As we already know (based on rumor and speculation, of course) is that it's going to come equipped with two cameras, one front and one back and will likely run FaceTime.
Now there are two more pieces of information to add to the rumor mill: It will be available within a few weeks, and it will have Apple's beautiful Retina display.
Again, this is all rumor, but many of the additions make sense given the natural evolution of Apple's iOS devices, and taking into account the features of the iPhone 4.
Perhaps we will know at Apple's next press event.
