I don't think I recall many people claiming HD was a gimmick? There was an obvious benefit to those with large screens - SD and HD, no comparison on a screen 37in and up.

Now, 3D - causes health issues, many people can't see it properly, doesn't work very well on smaller screens or larger screens at a distance of more than a few metres... the list goes on.

The high numbers of 3D TV sales is completely artificial, as many TVs come with 3D as standard. There's simply not enough content or interest in 3D to justify the broad existence of 3D TVs.

Until they iron out the "teething" problems, then the majority of consumers won't embrace 3D and will keep it for the novelty movies in the cinema.
