 It's Tuesday, October 30th, 2012. I'm Billy Disney, and this is 90 Seconds on the Verge, brought to you by Virgin Mobile. Microsoft has sold 4 million Windows 8 upgrades since it went on sale this past Friday. That's according to CEO Steve Ballmer at a keynote address today in Seattle. Those numbers are only for upgrades, not new hardware. Ballmer also mentioned the launch of Surface, but did not release any sales figures for that particular device. New details have emerged about Scott Forstall's exit from Apple. Sources tell us that the ambitious and abrasive head of iOS had enemies inside the executive ranks. Legendary Apple designer Johnny Ive and Forstall reportedly clashed over the use of skeuomorphic design. It'll be interesting to see how much of that remains in the next version of iOS. Reportedly, the last straw was the new maps. Forstall believed the complaints were overblown and refused to sign an apology letter. That duty ultimately went to CEO Tim Cook. Forstall cashed out $38 million in Apple stock earlier this year, so his landing is expected to be a softball. Finally, Disney has purchased Lucasfilm Ltd. from George Lucas. The deal is reportedly worth $4.05 billion and will include all of Lucasfilm's assets, including the Star Wars franchise and businesses in quote, live-action film production, consumer products, animation, visual effects, and audio post-production. Disney also announced plans to release Star Wars Episode VII in 2015. George Lucas himself will serve as creative consultant for the new film. No word yet if you'll be able to go to Disney World and get your picture sitting on the lap of slave Leia, but I'm gonna try. That's it for today's top stories. Tune in tomorrow. And for all those affected by Hurricane Sandy, please stay safe.
