...and I've heard they are in fact coming out with another version of the hopper with you guessed it another tuner, will only require a single line from the dish to the node (thank god) or so I've heard but that could be office rumors.
Sorry, but that is not believable for DishPro Plus technology,which only allows two tuners/cable. Now, they could change that with something other than DishPro Plus LNBs or switches ahead of the node, but I don't see that happening any time soon.
