I am not aware of any official statement about a commercial TAGE implementation.
But comparing Haswell's performance counters with the output of a TAGE simulator, we observe comparable branch misprediction rates on average. (http://hal.inria.fr/hal-01100647/)
Incidentally, at ISCA 2012, André received an Intel Research Impact Medal for his "exemplary work on high-performance computer micro-architecture, branch prediction and cache architecture, [that] has been of tremendous benefit to Intel, the industry, and the academic community as a whole". :)
