If anything, Old Country should be kept & expanded; there are still ride pads & queue areas behind the bumper cars.
Fantasy Fling, last I heard, is up for sale. It's also rumoured that Musik Express could be leaving as well.
The park generates more revenue than you could ever imagine with the picnic grove; they'd be insane to eliminate it.
I think Movie Town should go from TDK over to (and including) the remaining portion of LTSP and re-theme it all to the Justice League, so people of ALL ages can enjoy JLA themed rides; you'd be surprised how many 3-6 year-olds like Superman and Batman...
