Google event this week more to it than you think
Yeah they said no new hardware will be revealed, but said nothing about software. Who's to say they won't reveal 4.4 this Thursday? Honestly, if all they have to offer is Google Play Newsstand, that's a waste of an event and a waste of everyone's time, so I'm sure Google has much more to reveal this Thursday than what they let on to everyone.
Plus, did it not occur to everyone...that everything is Google Play related? All hardware is sold on the Google Play Store, all software deals with Google Play Services. I don't know about you guys, but I have high hopes for this Thursday, and I'm 100% sure they will reveal 4.4 at the very least.
