While no official announcement has been made by either party, Motorola has reportedly acquired 280 North, a startup known for developing the Cappuccino programming language.
TechCrunch claims to have confirmed the acquisition, and has heard that the price is around $20 million, though this is not confirmed. Michael Arrington shares this quote from a Motorola spokesperson:
"I can confirm that Motorola acquired 280 North earlier this summer. The transaction provides Motorola with specialized web-app engineering talent and technology that will help facilitate the continued expansion of 
Motorola’s application ecosystem. We believe 280 North will be instrumental in helping us continue to foster the Android ecosystem with innovative web-based technologies and applications. Terms of the transaction were not disclosed."
It’s interesting that the acquisition apparently occurred some time ago, and that neither company has made this public knowledge. In fact, 280 North hasn’t updated its corporate blog since March.
280 North did have a presence at Google I/O (the company’s developer conference) back in May. There, 280 North showed off some integrations with Google services.
