No, you won't get it in your next mirrorless Canon camera ;-) Canon press release:…
Another exploded Nikon D800
Canon may have problems with the light-leaking issue of the EOS 5D Mark III, but Nikon has also some problems to deal with. Nikon’s new full-frame flagship, the D800, is reported to “explode”. This is the second forum post I found about this issue (another one here). So, if you want a new FF camera you can choose between one that’s leaking light through the top LCD panel, or to get one that will explode in your hands. :-) Hard times for photographers!
UPDATE [thanks to Bobby]: nikon rumors reports that Nikon is recalling batteries that are used on various cams, the D800 included:
Today Nikon recalled some of the EN-EL15 rechargeable Li-ion batteries […] that are used with the Nikon D7000, D800, D800E and Nikon 1 V1 cameras. The described reason for the recall is overheating. There were no overheating cases reported from users, the problem has been discovered during the manufacturing process.
