There is no "Google now look". Its still holo
Many people make the mistake of not understanding that this so called "Google now" look is really holo 2.0. Gone is the 2011 tron look with a look thats more clean and shockley hard core android users like. Its an evolution of holo. Google just spent little over a year getting a standard look for android. They are not going to toss it out the window. Not for another few years at least.
