Okay, so let's recap:
We know:
The Doctor lies
River lies
Moffat lies
McGann lies
Does Eccleston?
So far, they're all proving the other doctor, House right. Will it continue?
There's certain writers, actors, creators, that I expect to give me non-answers, or statements with 5 different answers to keep secrets, and those I expect to to tell me anything to keep a secret and those that won't play at all. I would expect Eccelston to avoid the question if he was involved and I might have hope of Eccelston giving me an answer that could be taken 5 different ways, but, Eccelston outright denying something he's actually involved in, that would really take me aback...
