In the situation you described, I+ would not wait for a new OS. If there were a sufficient number of TPM PCs, and I was concerned about the security matters raised, I would start using the tools. The OS ( and I assume you mean Vista) would not really add much to the situation that is worth waiting for. Everything you need is available today to get going.
Now if instead you asked will companies stop buying any PCs until Vista is available, then that's a different question. I think that may have had some merit in the past. However given Microsoft's track record and the noted expected delays, a company would have to be crazy to simply wait, do nothing and hope that it will become available sometime in the future.
