I am not sure whether that article came out before the announcement or not. FWIW McLaren is using a DCT (with no MT available) in the MP4-12C whcih has 443 Lb/Ft of torque.

I heard ZF engineers speak at a presentation and they said that they expected that future versions of "traditonal" planetary gear automatic transmissions would rival and perhaps match the peformance of DCTs. They also felt that a torque converter is a very good device for smooth starts and as long as they get locked up at low speeds they have negligable effect on performance and efficiency.
