I'm guessing as contracts run out, some channels might get dropped.

These were all pre Rogers. I wouldn't be surprised if these disappear. As for HD channels that aren't carried on Rogers, I would imagine Source Cable will retain them even if Rogers main areas don't have them so long as at least the SD version is offered on Rogers other systems. Since Rogers is aggressively moving more channels to digital, I'm guessing more HD channels for the main Rogers systems are on the way.
I still don't get why Rogers is holding out adding channels to it's other Hamilton system now under the Rogers brand. They have more than enough bandwidth. Shaw dropped all the upper tier analog channels before they transitioned the system to Rogers and Rogers has added almost nothing since taking over, just whatever was mandated by the CRTC; Unis, LCN and Cable 14 HD. They don't even have the extra TSN feeds.
