Yeah we mentioned it in the lead. It's only been around 2,5 days with the new cards befor this article was written, so there just wasn't quite the time yet for cards to break into the meta.
I suspect next week might see more movement as people will have had more time to experiment and Shaman will get 2 solid cards, which might lead to a resurgence. Then again, the current decks are all well entrenched and successful so there's also not much need for people to experiment.
It's been a long while since we had a set that did not shake up the meta significantly so I'm still pretty confident that a shake up of some kind will happen. We'll just have to wait for it to be reflected in the top decks we see in the meta.
