Ok I've done some reading about the ND-TMC10 traffic tuner that will be optional for the 930 and it is stated several times that this tuner will be "included" with the Z130. So if this is not a typo, it indicates that it is still an external add on but is included with the unit. If this is the case then this should be the 110/120/920 owners traffic solution once you upgrade to the 130/930 software. Jason, is there anyway you can confirm this with anyone from Pioneer?
The traffic tuner is the same external box (ND-TMC10) for both units, it's just included when you buy a Z130.
