It will be like the new adwords. Looks pretty, but is missing half the features and eventually..once it comes out of its "beta" everyone who's been using this tool daily, will regret not staying on the older version.
I hope it won't mean less feature. However, I don't like the new Adwords either, the UI is better, but the whole UX is a crap, I have to read tons of articles to find the good old features.
