Another concept I saw. This one is pretty neat

From here
Also for the ones who don't understand, concept and rumor means 2 different things. Concept ideas are just ideas designers (or anyone) came up with but are not actually true. These concept ideas, can become rumors after someone misunderstands the meaning of what they saw and decided to spread the word that what they saw is real.So in short, yes, concepts are fake until it goes into production.
