It sounds a LOT more like LA Times is trying to create "Will Princess & Frog happen again?" [MarkTwain: in terms of being a box office flop] (for no other reason than it was "supposed" to happen right about this point in the script), and took some comments out of sensationalized context. Strong words, considering it hasn't even opened yet.
Disney and Catmull certainly want to play up the "It's not your average Disney film!" spin to head off people complaining about the style, and working in the idea of making "newer" films -- But "We don't currently have any on the docket" is NOT the same as "We've barred them at the door": "Yes, we have no bananas" is not necessarily the same as "The government has banned bananas by law."
Ed's comments about "We wanted to try something new..." are almost immediately followed in every single citation by the Times reporter spinning it as "Pack it up, folks, it's over!" That sounds a lot like an article that's frustrated it's not quite getting the story it set out to write, and hoping they can still patch it together in the edit.
