New Microsoft brand logos, company tagline revealed at MGX event? (update: no new logos, tagline is a go)

It looks like Microsoft may have revealed something big at its annual MGX (Microsoft Global Exchange) event, namely... new logos for its main brands and a fresh brand motto. "Be What's Next" touts a teaser which has been posted on YouTube, along with a fast moving sequence of morphing logos, shuffling from Windows, to Windows Phone, Xbox, Bing, and finally the familiar Office logo that's been kicking around for a little longer. It's unclear if these are just treatments used for a promo at the event, or if this is a signal that Redmond is dumping its familiar (and frankly dated) iconography for something a little looser, leaner, and hipper, but we can't say it would be a bad thing. It would certainly make sense against a backdrop of potential comeback in the mobile space, gains in search, and the seemingly successful (or at least satisfying) Windows 7 launch. One thing is for sure, MGX is a corporate, non-public opportunity for the Microsoft faithful to cheer the brand (Ballmer received a 30 year commemoration at MGX 2010), so this would definitely be the place to unfurl some new branding.
