I predict that the Keurig 3.0 will be Internet-only. Using an expanded Hyper Text Coffee Pot Control Protocol: http://tools.ietf.org/html/rfc2324 for management. Surely no DRM opponents can complain if they're using standardized protocols.

Using an app on your phone, you'll scan the coffee pod you want to use (your phone takes a picture of you via the front-facing camera as a security measure; much like ATMs have cameras); this connects to the central Coffee Server to generate a one-time passcode. Then your phone does a BREW via HTCPCP to the Keurig, providing an K-Authorization header. Having the encryption key for the one-time passwords be stored on the server avoids the mistakes problems Sony etc. have had where private keys inside devices are compromised.

Requiring a smartphone could present interesting branding opportunities, e.g. co-branding the Keurig 3.0 with iPhone 7, social network integration (click once to post the coffee you're drinking to Facebook), automatic reordering and possibly integration with health services as your coffee drinking data can be shared with your health care provider who can adjust your insurance accordingly.
