Android: why no focus on design?

After the last couple weeks I'm really concerned for my future with android. I really like android and the way it is improving. I also like the design of stock android. But in september the Lumia 920, the iPhone 5, the Samsung Ativ S and now the HTC Wp8x were released and all have one thing in common: a focus on hardware design and style. All of Samsungs Android phones are mainly made out of not so nice plastic - yet their WP device is made out of aluminum. The only nice android that comes to my mind is the HTC One X which is unuseable for me because of sense.

It's getting harder and harder to stay with android for me because of all the uninspiring phones. And hoping for one good Nexus device per year is not an ideal situation. And if the trend continues and the next flagship phones are all 5 inch phones I really don't know what to do. It's a shame because I think it's the best OS - if just hardware manufactureres could for one second focus on design and not just that asking too much?
