So... you're seriously suggesting that just because not everyone would benefit from something, they shouldn't bother?!
My personal opinion on the matter is, until they finish the HD rollout, with 100% HD for all channels, they should not waste money on it, unless they plan to use their 3 transponders on 110 for a 4K ESPN3D with Smell-o-vision. I would be highly put off if they expanded their niche formats further before at least matching the rest of the providers on basic HD.
I would actually prefer, for a format that is so bandwidth intensive, they just start a new company, launch its own satellite (how about 101 KA?) and put all the niche format (4K etc) on it, so those that have the money to buy 4K monitors can support the effort to broadcast it.
