EOS 5D Mark III Hardware Change Rumor

The latest I heard about the 5D Mark III says that new batches that are shipped have a thicker top LCD panel cover that looks a little different than the one mounted on previous batches. Don’t know if it has to do with the light-leaking issue that has been observed on some 5D Mark III bodies, or if it has something to do with the rumored recall/stock delaying of the Mark III.
