Brad - I asked about the SB-910 myself and got a similar reply. The PW rep said that, while it might work, I should expect that there would be some malfunctions in actual use. He offered no schedule for getting the firmware update that would let the PW's and the SB-910 work together in TTL mode.
Rather than buy another speedlight right now I will just wait on the new firmware. Hopefully that won't be too long.
