Honestly, I would be surprised if TWC puts live programming in the afternoon long form slot.  I mean, who is watching the channel then?  Your average viewer is probably at work.  As far as cutting live programming after 8 pm, that really screws over west coast viewers, as live programming now ends at 5 pm pacific time.  However, I think TWC is going to try to compete with other networks by showing series in prime time.  "Catch a new episode of [whatever], weekdays at 9pm!"
Plus, as previously mentioned, if the 1 am WCL was a replay of the 10 pm hour, then what's the point?  BTW, it looks like the renamings have the word "Live" cut from the WC name.
