Google TPU: when/how will it be available to me? Google recently announced the TPU custom chip.

They stated it is available in Google Cloud Platform, but only for their internal usage.

When will I be able to use it? Will it be possible to buy this chip or will it be only accessible through their cloud?
Google has apparently said it would not be available for sale outside of Google.

Google also did mention it would be available to developers for Tensorflow and Cloud machine learning but otherwise it has been light on details or when this will become available.
