Seconding this. The markets aren't spectacularly and miraculously efficient, but they're efficient enough that products without demand will not last, with the exception of industry-wide collusion to remove the consumer-preferred option from the market. Game theory says the existence of a wanted-but-not-provided product probably won't last, however. And regardless of continuous cooperation of the participating suppliers, there can always be a new entrant. Anecdotal on the TV point, but I recently purchased a new TV... no bend, no 3D (didn't even see that as an option), no hassle. :)
