It looks like MTS got ahead of themselves in terms of promoting the launch of the new channels. Although they obviously do not have control of when the channels will launch, I think including the channels in their promotional information and online package selections is deceiving. Fortunately most of the channels that haven't launched are in the Free HD section and not costing any extra per month. The only change is the movement of the National Geographic and Showcase channels out of the Free HD package, which is now costing you $3 a month with the addition of MovieTime HD and History HD, although with the omission of HGTV HD. Is it worth it? I think so. I don't think Wild and Discovery are worth $4 a month and therefore do not subscribe, but others may love those channels. It's a personal choice.
Overall, I think the biggest issue for MTS right now is the way the channels are packaged. The HD packages are including channels from all different SD theme groups, causing you to need a huge number of SD packages in order to receive all the channels in the HD groups you're paying for. I miss the "Digital Favorites" package that I had with Shaw Direct, giving you all the most popular SD channels. You still had to pay extra for the HD theme groups, but at least you had most of the channels required already to get the new HD equivalents.
Just my 2 cents.
