While all of that makes sense in some respects (for example, the apparent refusal to approve attractions not based on IPs), what goes against this is the amount of money they spend once something does get approved. For example, they left DHS to decay for a long time but then seem to have showered money onto Toy Story Land and its two very basic attractions. The same goes for what are apparently astronomical amounts being spent on the Tron clone in MK.
The difference with at least the last half of Eisner's tenure is that he seemed to approve a lot more, but he at least appeared far more ruthless with cutting costs to the point where you got parks like DCA and WDS. Iger seems to have, at least until recently, approved less. But, when he does, the cash floodgates open.
