I for one can say, having worked for large companies can see that things like this are on the to-do list up on the white board.. and things come up that either delay or shelve items on that to-do list. It generally doesn't mean the items have fallen off the list, but not working with their company on a day-to-day basis, I am not sure what they are tasked with. For all we know, members of the Star team are overwhelmed by building configs for HD stars and other things are told to wait. They have a very talented group of people, but at the end of the day, there are only so many hours to work on improvements / configs / deadlines / due dates / etc. As with telling viewers insider information, they aren't obligated to answer such answers (like deadlines, or due dates), and I would feel the same. Viewers (or customers) only need to know what they need to know.
My 2 cents
Wow, a ton of broken promises from TWC regarding the LOT8s. Analog signal with legacy STARs remains, no graphics update to the IS Jr, and no music changes. Since the sources where you all got this information seem to be reasonable, this either means that TWC couldn't care less about this aspect of their station anymore, or that they're giving BS answers to their viewers about date changes, future plans, etc.
