I don't watch TWC as much as I used to - namely because I don't have a lot of time. However, since I found out they were doing a relaunch of the channel, I've been tuning in a lot more. I like this overall look and I can't wait to see it in action.
I'd imagine the update for the local forecast would go to both the Intellistar and the I2.
Another question is what kind of surprises will we see when they are updated? When the Intellistar was updated when they launched in HD, it had a new style LDL and instead of my location of Pittsfield, it had Bousquet. It was fixed a short time later.
