He's just got less to do of his own accord so far; think about it, none of these are specifically Littlefinger plans; wait for the Tyrell alliance.

I've actually been quite impressed with Gillen's performance so far, specifically when he's angry at Tyrion in Garden of Bones: I'm not sure if he did this intentionally or not, but notice that the actor shifts from a formal Received Pronunciation accent to his native Irish accent when he is flustered and angry. I'm not sure if this is just how Gillen the actor "does angry", or if he consciously decided that Littlefinger shifts back into his relatively provincial accent (from the outlying poor regions of the Vale) when he is upset.
