I am not too worried about it. I suspect that only governments would consider spending the necessary money and effort to break into any given TPM, and even then only under very extraordinary circumstances. Also to crack the TPM it needs to be in the hands of the cracker. One reason to get and use an encrypted system is to protect your data from hackers as you use it. The theft of an important laptop in a government or corporate environment, if reported quickly, should allow the organization to exclude that unit from its system.
The counterfeiting of TPMs for production, however, could be a major concern.
