The quote below taken from Gearlog.com seems to suggest that the possibility of Bluetooth being included in the new iPod Touch is out of the question, and also that games development is not currently on the agenda.
The iPod Touch does not have Bluetooth. Any images on the Internet that may have implied that it did were errors, Joswiak said. Also, there are no games coming for the iPod Touch right now.
This is dissappointing on both counts, however I still don’t see this being a barrier to third party …
