At least one sighting of yet-to-be-announced WebOS 2.0 has emerged inside the usage statistics for a WebOS Foursquare app, according to its developer.

When rummaging through the stats to discover the penetration rate of 1.4.5, he came upon one entry of 2.0, codenamed Roadrunner, though any other information is scarce at the moment. It may very well be an emulator, or someone hacking the system (though unlikely), but it could, as a best-case-scenario, be some Palm employee testing out the new OS on brand new hardware. With unicorns.

HP has claimed, since buying the company earlier this year, that development on the OS will not stop, and they will continue to honour their hardware and software roadmaps.

If you can recall, the Palm Pre and WebOS were announced together at CES in 2009. One and a half years later, that hardware and software are looking aged indeed.

Let’s hope this Roadrunner actually materializes, and doesn’t fade into smoke like the cartoon of the same name…
