I don't think even the content providers or hardware manufacturers think of 3D as an "all-or-nothing" situation. The truth is that, for all of the people for whom current 3D tech doesn't work or simply those who don't care for it, there are a great many who enjoy the extra kick that WELL-DONE 3D can bring to entertainment. Like any extra layer that is added to original content, it can be utilized poorly. 3D is far-more-complicated to successfully implement than the majority of content providers realize. The down side is that, if it's done exceptionally poorly, it can cause people to puke. We're currently in a learning phase when it comes to 3D. Yes, stereoscopy has been around since the 1800s. However, it has just reached the point whereby moving images can be shown with next to no distracting flicker, improved polarization technology, and relatively inexpensive hardware. That's why I think 3D has the potential to be around for a while, as opposed to the brief spurts we had in the 1950s and 1980s.
Yes, I'm a fan. I'm also a realist in that I know that 3D isn't effective or proper for every form of visual entertainment. I think it has great potential for gaming and am excited to see how it is used. I think it can be fantastic for films where a primary aspect is visual impact. That said, there is never a need for MY DINNER WITH ANDRÉ: 3D or SOLITARE: EXTREME 3D. Content providers know that, as well. Sure, we'll see plenty of releases that have 3D tacked on for no other reason than the money men insist upon it or the creators of the content are incompetent. Eventually, though, I think things will settle down and 3D will find its place as an option for those who wish to take advantage of it. I don't think it will ever be pushed as a complete alternative to 2D, nor do I think we'll see games or films released solely in 3D, unless the structure of the game or the nature of the film demands it. There are far-too-many potential customers who aren't fans of 3D. The content providers know this. They aren't about to alienate such a large potential source of income. I think 2D and 3D can live together quite happily together. There is always the chance that any number of factors such as bad marketing, a glut of awful content, high cost, or Pokémon seizures could sink 3D in the home. I just don't think it should be automatically dismissed by those who dislike it. It will be interesting to see how it pans out.
