The DT/C300 thing is very fuzzy. It's been said that it's a "strategic partnership" where Phil is pulling double duty with both companies but DT's stuff is still its own, with C300 providing manufacturing. Others have claimed that C300 owns DT outright (like they do with Track).
Without seeing the details of the contracts (and even then unlikely), and without seeing a press release free of BS buzzwords like "strategic partnership", whatever that means, we'll never know.
