According to the updated transition plan, pretty much every local will be in HD along with the majority of specialty channels. Some channels launching this year include TMN Encore 2 HD East, MTV HD, Canal Evasion HD, Super Ecran 4 HD, Max HD and Musique Plus HD.
This is the 3rd or 4th revised plan so I expect more channels and obviously channel launches or shut downs will also change the plans too.
Shaw Direct could very well have the best HD channel lineup by 2019 with the availability of all the locals but will it even matter by then? I still wonder if Bell is going to announce something similar soon. I'd imagine a lot of their residential and commercial legacy hardware is also approaching end-of-life support too along with their MPEG-2 encoders.
