I think Wonders of Life should remain open until it is given a decent and substantial rehab in the attraction's "spirit." And that's assuming a lot (if not too much) - that it would be given a decent rehab.
However, I have no indication - besides educated speculation - that Wonders will reopen after its current run (Dec 18-Dec 31). One rumor has it closing for good after this. In any case, Disney has made a nice tax write-off by making WoL seasonal; they've operated the interior every day for sunlight, I hear, and Cast Member socials/conventions. Oy.
