I'm still watching the keynote thing and he makes some good points but for then backs them up for the wrong reasons. Like how you can't use an old design for a character because it'll never be as good as the old one under the current budget. What about just changing the design to differentiate the product?
Then he discusses format (using the Looney Tunes example again) by saying that making new Looney Tunes under the old format (three shorts) encourages the viewer to change the channel. That could be true, but at the same time I've seen people keep the channel on the old Looney Tunes whenever they came across it simply because the current short airing was only 7 minutes long and they had no commitment to watch the rest. And while they sometimes changed the channel afterwards, they'd sometimes keep it to see who was starring in the next short and what the next short was about. Alternatively, if you find the longer show you were watching was dull, you could easily switch to Looney Tunes and wait for the next short. I believe there is a market for shorts and my main problem with the new Looney Tunes from what I've seen of it is that the stories tend to wear out their welcome by the end of the episode. The old format worked for not only the old Looney Tunes but many of the WB releases in the 90's as well (Tiny Toons, Animaniacs, etc., while still occassionally having longer episodes when the story called for it).
