Why don't you support USB or Bluetooth OBD-II interface hardware?

We have investigated the new hardware integration features of iPhone OS 3.0, which in theory allows us to support Bluetooth and Dock connector-based hardware. However, after confidential discussions with Apple, we have concluded that WiFi is still the most reasonable option at this moment—both from technical and business perspectives.

We will not be supporting Bluetooth or Dock Connector OBD II connections yet—but we continue to persue this option and will announce any updates as soon as we have them.

Seems like an interesting product, but I already have a SGII and don't want to go spending another $200...
 
The thing that bugs me the most about the SGII is the gauges are a little slow to update. Rev seemed to be *much* quicker in updating (e.g. boost gauge that's actually useful).
 
Any clue which ones work with cheaper OBD-II interfaces? Not looking for the most advanced one out there, just someone for general stuff. Already have separate stuff for the more advanced stuff.
