I'll chime in with an example.
Today, Dreamers in Minnesota had it's first 5 proxy tournament.  There was TONS of Dragon and Hulk/GAT.  Yet, almost zero Trinisphere, Crucible, or 'Juggie-Workshop' decks.  There was a fair share of Mirrodin modular/affinity decks, but in comparison to alot of other metagames, there was a real lack of 'big artifact decks.'  IMO, the meta hasn't caught up to present day.  
Is the cycle changing again? Please, discuss.
I think it is inevitable that gay/r and to a lesser extent, 4cc will take a hit with the advent of Crucible.  As long as 'Shop decks can go: turn 1: Mox(for Daze protection), Workshop, Crucible/Trinisphere; fishy decks will be at a disadvantage. 
Then again, the general meta is really focused on good artifacts because Mirrodin is the latest block and craze.   When Kamigawa hits, people may set aside some of their artifacts in favor of new tech.
