Android 4.4 and the next Nexus device are pretty much the only new topics I can remember attempting to follow in the news recently, and it's just ridiculous. When I bother to look I see a solid dozen new articles every day regurgitating the same speculation, with and without sources.
I don't know if these shots are new, but considering this is the second to last paragraph...
With all that said, we’ll note that these screenshots hardly confirm any of the recent Android 4.4 details we have talked about – not that those are any more official. We’ll again add that we’re not looking at a confirmed Android 4.4 build here, so take everything with a grain of salt. And finally, even if it’s an Android 4.4 version here, it’s most likely an older one – from mid- to late August – which means things may have changed since then.
...I just can't imagine why anyone would follow tech 'journalism' if this is what it actually amounts to. "Here are some exciting photos... of we're not sure what."
