I agree, the entire time I had to remind myself not to read that in Matt Smith's voice. But then, this is hardly indicative of what they have planned for the new Doctor, and indeed kind of fits with the other post regeneration scenes in the nu-series in which the new Doctor still has his predecessor's mannerisms. Smith seemed to be channelling Tennant in The End of Time, and Tennant was channelling Eccleston in The Parting of the Ways.
I'd argue that Smith was channeling Tennant as late as "The Big Bang," at least in Moffat's scripts.
