In a Worldwide Developers Conference keynote dominated by iPhone news, Steve Jobs did offer bit of OS X-centric news to attendees: The next version of OS X is code-named Snow Leopard.
But that's all Apple disclosed about the new OS during the hour-and-44-minute keynote. Jobs said more information would be available during the conference's afternoon OS X State of the Union session; however, like every WWDC session save for the keynote, that discussion is held away from the public eye with its contents covered by a non-disclosure agreement that prevents attendees from talking about what they're told.
Rumors about an OS X update code-named Snow Leopard surfaced in the weeks leading up to WWDC. According to several published reports, the rumored update was expected to be for Intel-based Macs only. It would offer few new features, focusing on speed and stability improvements while unifying OS development across Apple's Mac, iPhone, and Apple TV platforms.
Whether those rumours are grounded in fact remains unknown after yesterday's keynote. Whatever the plans for Snow Leopard are, they'll remain under wraps — at least until Apple decides to disclose them.
