Lol...just type ipod touch 3rd generation on google...the web is the source.
Your premise of finding the exact source is flawed from the beginnning.

Why?
Because Apple doesn't reveal any secrets until the announcement date which will be sep 9th. (the date has been confirmed from various reliable sources with the upper apple management having an empty slot for that day (due to the announcement probably at yerba buena or somewhere nearby in san francisco (my hometown right now))

How do I know this? I have done extensive research on it and a lot of facts to back it up.
Camera is there (all 3rd gen cases of touch come with holes for the camera)
If video is enabled, the mic has to be there.
BT is a standard feature now.
Only thing hanging is a GPS (prolly not there for now) and an OLED screen (that'd be really sweet). A faster processor and a 16 GB for at most $219 is guaranteed. Many sources say it might be $199 and I won't be complaining.

Also, if you are buying the touch, I have done a lot of research at the kind of apps which will make it a super PDA plus much more.
Let me know.
