Well it does provide them with a sort of "market viability" test. Leak some information to see how the world reacts, and then decide if it's worth proceeding or not (obviously not, in this case).
Trying to overhang the market may be trendy, but it's certainly not new.
Anyway, in the absence of any reason to believe that this thing, whatever it is, will solve some problem in a compelling new way, revealing it's existence doesn't accomplish much. I'd say it seems more likey that this is simply a mistake, rather than a weak marketing stunt.
very true...its all Mktng gimmick....this strategy offers free publicity. See what happend to iphone4...huge hit after " Being left at a bar Accidently :D "
