Let's not make the mistake of thinking TPM means Wave--far, far from it. TPMs could (although highly unlikely) become the dominant security solution without Wave prospering at all.
Wave has to sell its TPM-based wares in a market where no one knows what a TPM is, if they have one, how it will used, etc--that's a tough uphill sell.
At any rate, success for TPM usage, if it ever arrives, does not mean Wave will succeed.
