Sounds like we're in agreement

I do agree that they would be putting in very big, blinking, neon letters that they now have MLB EI. The lack of these sports packs is a killer for them. I know why they're putting the channel lists out there - but I do believe there are some mistakes (e.g. TMC HD is no longer listed as a channel, as someone noticed). The reason has to do with the channel number changes, and not really for the new channels. They're required, as per their franchise agreements, to notify customers 30 days in advance of any channel deletions or number changes (additions have no such requirement).
If you go to their channel listing area, you'll notice a message at the top saying that the new lists are there, and will be added per market about 30 days prior to the channels being rolled into that market. I believe they're treating THAT as their 30-day advanced warning notification to customers.
I also wouldn't be surprised if there were some additional channels there when they do roll out. There are some suprising exclusions - e.g. they added all the Discovery HD channels... except Travel HD? That doesn't make any sense to me, and I think it's a mistake. Also, I saw no FX HD, nor any Fox Business HD - Fox is strangely absent from the list of HD channels being added. Ditto ABC (no Disney HD at this point, e.g.). I'm not sayign that any of those channels will be there this summer, but it wouldn't surprise me if there were a couple more that show up that aren't currently on that channel list. Guess we'll just have to see.
