As a developer, I can sympathise with the long phases of initial planning, developement and design (due to everyone, including lawyers, getting their input addressed) and approvals, but I really think that WDI "milks" the construction phase. Once all the legwork has been done, and the construction plans are in the contractors hands, the process should move quicker than it does in the "Disney" world. I think that Walt would be extremely frustrated at the pace at which things move today with regards to WDI and bringing new attractions online.
Now if this is due to budgetary constaints (in which quarter or fiscal year is this part or that part of the project going to fall under), I find this even more frustrating when considering the size and profits of the WDC. For all we know, there could be just a fraction of the labor needed to complete the FLE, and they just keep getting shifted from one piece of the project to another, to keep each piece of the budget on track. Have we actually seen crews working on every piece of the expansion at any one time? Seems like they're over here one day, and the next, they're over there.
Go figure....any way you look at it, it seems to be taking an awfully long time.
