OSX 10.9 has begun appearing on the Interwebs, though it hasn't been announced by Apple. A Czech site first reported that Macs identifying themselves as running OS X 10.9 began appearing on on its servers, and AppleInsider and The Mac Observer found instances on our servers, as well.
OS X 10.9 Lynx?
Apple currently has OS X at version 10.8.2 under the marketing name of Mountain Lion. Mountain Lion shipped in July, just four months ago, and the company hasn't yet announced its successor.
Apple has been on annual release cycle for the last two versions, Mountain Lion and Lion, and the company gave no indication of changing this schedule at World Wide Developers Conference 2012. Macs running early versions of the OS therefore isn't all that surprising.
That said, it's always possible that someone out there is simply putting in a fair amount of effort into getting Mac sites giddy at the prospect of OS X 10.9. Spoofing one's identifying data isn't all that hard, and from there its simply an issue of pulling up a few webpages here and there.
In that it's not that big of a deal either way, that seems doubtful. We should also note that OS X 10.9 first started showing up on our servers on October 22nd. AppleInsider saw a few hits the week before, while Letem světem Applem (the Czech site) reported hits starting in September.
