The new chipset on the 2nd Gen iPod touch has been found to include a Bluetooth Chip.  The Chipset is capable of BT2.1+EDR which generally means that it can use A2DP for wireless streaming of songs to your bluetooth headset.  FM is also supported, but Apple generally has not included FM in any of its iPods.  It would be great if this was part of a later announcement, perhaps October?  Anyway, lets cross our fingers and hope Apple enables the chipset to allows A2DP and FM or at least A2DP.  Also,  The Nike transmitter uses the same frequency, however the software is supposedly going to work with iPhone and that has BT so it could be either or.
