Just jumping in quickly (will get to your original comment in a moment).

It's like using the Daleks every year.
It should please you then that Moffat has said he's not going to use them for the foreseeable future, talking about how they're the most constantly defeated enemy, and he rather wonders why they even bother anymore. *g* (Although they got away in the last Dalek episode, which I rather liked.)

Right now all I care about is whether my cracktastic River Song theory is correct.
No theories plz! Just in case you turn out to be correct...
