There's a number from the list missing like Bite, Salt + light, Grace TV, Cult Movie Network, IDNR-TV, HPItv, EuroWorld Sport, CPAC, and the porn channels.
But, I think Action will most likely go HD and even DIY. And I think ZoomerMedia during the mandatory carriage hearings mentioned that they planned on launching Vision TV in HD. I'm not sure the date but I'm assuming 2014. I think Mystery is just too much of a rerun channel for them to bother launching it in HD yet. And I don't see MTV2 launching yet either as it's really a worthless channel. They've even given up maintaining a decent website for it.
But I think if any of the channels above owned by a large vertically integrated company rebrands, that will be the point when they may launch an HD channel. And I think Fashion and Bio are good candidates for that this year. I would have said Book, but since Bell was denied allowing more scripted content, they may take a little while longer to try to figure out what to do with it.
