Not really - remember they don't need to invest a lot.
Define "a lot"... Every 3D channel takes bandwidth that could have been an HD channel that everyone can watch or about a dozen SD channels.
Right now Dish only has one receiver that officially supports 3D. To develop more would take money and time... and customers would have to be willing to upgrade to those receivers and that takes more money and time for Dish to create the receivers and get them installed.
The big problem Dish will have is people will leave in droves as 3D catches on and it is much more difficult (and costly) to get them back.
Really? People keep predicting this. Dish was the leader in HD at first, then fell behind for about a year to DirecTV. All that year people predicted the mass exodus of Dish customers... and it never happened. Dish eventually added most of those channels and now even has some that DirecTV still doesn't! (of course DirecTV also has HD that Dish doesn't too).
So... the customers are not going to suddenly run from Dish over 3D either... especially not now when the adoption rate is so low.
Consider... not all of the customers who own a 3DTV are actually using it for 3D most of the time. Heck, I wager there are still 3DTV and HDTV people in large numbers out there who don't subscribe to an HD package too!
So... a large investment in 3D when the customers seem lukewarm to it, seems unwise... when there is a limited amount of content and only a few channels right now... and Dish could jump in the game 1, 2, or maybe 3 years from now and have just as much 3D as everyone else.
Also, more time Dish procrastinates, more channels will go Directv exclusive. Then, where is dish going to get content from ?
That's not going to happen any more than HD channels went exclusive. Yes, there have been a couple of exclusive HD channels... but by and large most of them are available to all providers. Content providers would be short-sighted themselves if they limited carriage to one company while trying to expand their customer base.
I keep hearing about Dish investing in 3D, just how much would we be talking about? They already have a HD DVR that supports 3D, the 922, so they might actually make some money on upgrade fees and higher monthly lease charges from folks wanting 3D, besides a couple PPV's.
This works both ways... IF Dish saw a lot of people willing to spend $200 to upgrade to the 922, then they might say "hey, let's invest more in 3D for those customers"... but as the 922 has been slower to adopt, I suspect, that tells Dish that right now customers might want things but don't want to pay for them.
Are customers going to want to pay $5 more per month for a 3D channel? Nobody knows the answer to that I don't think.
A 3D SBS channel takes the same bandwidth as a 2D HD channel so if Dish has the bandwidth available they could add it.
Another twist here too...
People freak out about Dish "down-rezzing" their HD from 1920x1080 to 1440x1080... and want "full HD".... but then would be willing to take 960x1080 resolution in 3D? That seems odd to me.
