Seems it became pretty common now that company honchos are going to announce the good things via Twitter. Following yesterday's tweet by Andy Rubin, today Bill Cox, Sr. Director of Communications for Windows Phone, tweeted about the recent software releases which includes launches of Angry Birds, Kik and GoWalla. However, even more important is the last sentence of his tweet where Cox promises "a juicy surprise for tomorrow". It not yeat clear what it means, also the later tweets haven't given any further hints but it's rumored that it might be the release of the Mango Beta ROM (for developers only - for sure) or the availability of Mango developer devices.
Whatever it will be, it must be something good (or better should be something good) if the Sr. Director of Communications is teasing us with such a pre-announcement.
