Most likely around September.
No. Currently, there is no iPod Touch with a camera. However, this may be a feature added to the next generation (fourth) of iPod Touches, likely to be announced/released in September 2010.
Apple has not revealed any plans for when the next update comes.
The microphone is located at the back of the iPod next to the camera.
a preview will probably be released next January, just like iPod touches, every September almost.
Apple are no longer manufacturing 1st generation iPod Touches. 1st generation iPod Touches are now becoming severely out-dated. The next iPhone OS 4.0 software update will not be available for 1st generation iPod Touches because the hardware simply can't support it. This likely means all future updates (4.x & possibly a 5.0 update in the future) will not be available for this device.
Well, after the nano chromatic (Nano 4th gen) the shuffle 3rd gen was released. It is speculated that the next iPod will be an iPod touch/ iPhone 3rd gen coming out late June or July. ~Griffin There is the chromatic ( Nano 4th gen) and there is a ipod touch, iphone, and the new ipod nano th generation with a camera.
Next March.
Well when I got the iPod Touch 4G, I immediately thought of how it would be immediately replaced with a 5th generation. I was rather happy when I found out about the iPhone 4S. No new iPod! So now we KNOW next year comes with a new iPod Touch. But, you could just buy the iPod 4th generation and enjoy it while it lasts. Or, you can wait for the next one. (You could wait for the next generation and buy an iPod Touch 4th generation for REALLY cheap :D ) Your choice really...
No
No, but it is rumored that the next iPhone Generation will have a camera. We should hear more about it this summer.
No there has been no rumors about a new gen, there is no 5th generation iPod Touch as of this 2012. However, over the next years you may find new generations.
Not yet, but it will probably come out sometime this year or the next.
