According to the FAQ, Bluetooth isn't currently listed as a programming method.
From the document found here:

Q What type of communication does the system use?
A The new system uses proven 802.11 wireless communications. More features are being considered for future expansion including robot-to-robot direct wireless communications and wireless joystick operation.
Q Must they be tethered in order to apply/change certain settings?
A No, the new system will include the ability to do wireless programming. However, this may not be allowed in competitions (in the PITS) to avoid wireless contention with the field.
Q Will the new controller be programmable through a USB 1.1 or USB 2.0 port?
A No, it will use an Ethernet connection.
Q How do I download code to the controller?
A Using either LabVIEW or the WindRiver Workbench tools over a much faster wireless connection.

This doesn't eliminate the possibility of Bluetooth, but... I'd say it's unlikely.

The NXT unit (used by FTC and FLL) is Bluetooth-capable. The FRC controller isn't the NXT, though.
