I would think from a MARKETING standpoint if Dish were to put something in writing like Coming soon, or soon pending FCC or Patent approval, or what ever the reason.
More new Customers that are waiting on OTA would switch to Dish, knowing it is coming and when.
For now all we have from Dish directly is some guy on Video at CES saying it is coming this summer and that is well past due. Yes I know we have Scotts info but that is not from Dish directly it is a He said He said, its not official.
No info in writing makes some think something is wrong or to not trust Dish as they are being secretive about it and have something to hide. Maybe the "J" month really is January 2013
