This is one thing that I can't understand why they would ever close it. If they are truly planning to expand the Pixar presence in DHS, they could literally change the "theming" from HISTK to A Bug's Life overnight. Change the sign and...voila! Maybe they would/could/should touch it up just a bit more than that, but again, very easily done virtually overnight (with some advanced planning, obviously, to have anything new ready to screw down)...and obviously, much cheaper than going to the trouble of pulling it all out and replacing it with something else. I'm all for shiny, new and exciting new rides, etc., but for a park that needs something for younger kids, keeping the playground seems like a no-brainer.
I realize this doesn't answer your question, but the first responder did that, so I thought I'd just take the opportunity to jabber on for a bit...ha!
