As of now, only a select number of developers have been invited/accepted at the early look Palm WebOS and Mojo SDK program. Those developers had to sign an NDA preventing them from releasing a ton of information about the goodies therein, but the PalmWebOSBlog was able to track down a few tiny morsels of information.

Hit up the source article for all the details but in addition to the pictures below, they also learned that the Mojo SDK font is from the Coconut font family, there is no support for Far East languages in the SDK, the SDK will run on Windows/OSX/Linux and they explain how you can navigate around the emulator.
