The Verge has this article about how Windows, Office, and Microsoft got redesigned last year. And that Xbox, Skype, and bing are on the schedule this year. That they're gonna go with that flattened look they've been doing lately. And that they took heavy inspiration for Nike, where you know from the logo 'That's Nike,' without even reading the Nike word-branding.
That bing logo starts at like :27. I doubt they'll spend much time at the Xbox presentation talking about a Skype and bing rebranding. But well.. I do kinda like that bing logo. It reminds me of nature.. And bing likes doing nature wallpapers on their site all the time. So it sorta fits?. Neat.
Microsoft bought Yammer last year. Its some messaging business-program that was supposed to get merged with Office or Skype.. I forget. And I still remember this logo from a couple of months ago. Very hmm..
