I am more thinking in terms of:

  1. Best price/performance is tensorflow right now. So, the best software choice is platform X.  
  2. Then in 2 years.. Well we are using Platform X so tensorflow is clearly the best option.

In other words once you pick conv2d, you tend to also stick with whatever conv2d is optimized for. Which also means HW vendors love to help optimize popular platforms.

Others can make TF hardware too. Now that Google has opened the way, they will compete.
