Where's the market for 3D?
The recent take-up and future interest in 3D has been shown to be very low indeed - A number of (neutral!) industry assessments have shown this to be true in many locales across the globe.
The commercial push for 3D seems to be from those manufacturer(s) who also have film studio/prior content ownership - It appears to be nothing more than another "missed opportunity": these studios will NOT produce creative and original output, rather than use this technology just as a vehicle to re-make/re-hash those old titles.
Innovation shouldn't stop at the technology, the content must be innovative, too. From a technical perspective, current '3D' isn't truely 3D; a veiwer can't move around the scene to get a different perspective of their own, its just the content producer's take on what they want to project at you that you are allowed to see...
When you really stop to think about 3D, what does it add to the story, the plot, the sporting event? Is it truely worth the premium that TV/Player manufacturers/Studio owners really want to extract from you?
