take a deep breath... relax. OK, so the UI changed around a little... but its not too bad. Every time someone goes through a UI change, there is the eneviatble "OMYGERDTHISUIBLOWS" backlash.... it comes out, after a while, everyone gets used to it. Then down the road it changes again... lather, rinse, repeat.
From the looks of those shots, it is just making the mobile Play app's look and feel consistant with Google's current interfact approach. So what if its different? It'll be easy to get used to and as long as you can find and get to the stuff you need, it's all good.
