I think the dominance of blue aggro-control is best shown by this: The most played cards don't represent different succesful deck types that fight against each other...they all make up one deck/archetype ! Witness:

4 Ponder
4 Brainstorm
4 Sensei's Top

4 Counterbalance
4 Force of Will
3 Daze
3 Thoughtseize
3 Spell Snare

4 Tarmogoyf
4 Dark Confidant

4 Swords to Plowshares

19 lands

...a rather straightforward 4c build, succesfully incorporating 11 out of the 13 most popular cards in the format in one deck (probably not playing Wasteland though).
