According to the GMR thread, TSL is having even more changes considered. What's unclear is whether the changes will be positive or negative, although apparently the most recent art reflects the 5th incarnation of the area.
I'm thinking that the budget has once again been reallocated, and that it's now a question of where the funds are going, and someone's fighting for Toy Story to get some of its budget back. I could be wrong, though.
EDIT: I just saw that WDI is being reorganized (i.e. firing some people). Based on what
@SirLink said in the TCM thread, I'm assuming that the DHS plans are being looked at in conjunction with this. I have a feeling that TSL in particular is being looked at both to trim more money off of it (which is valid, the price tag is still ridiculous) while increasing the quality of what will be there.
Link mentioned that there's a back and forth regarding budget vs. reimagination of the area, which would fall in line with this.
