Kodak has just introduced a cheap, simple 35 mm camera (as well as a half-frame version) -- the selling millions bit is evading them, though, because film is still a hobby item rather than a consumer commodity.
Marketing something else as Kodachrome would be silly -- anyone who remembers the real Kodachrome would just shout from the rooftops about how this isn't it. At the very minimum, it would need to be a transparency film, and none of the E-4 or E-6 films has ever matched K-14 Kodachrome.
