Chances of sensors over-heating?

DPReview has a Photokina Interview with Canon Inc's Director and Chief Executive of Image Communication Products Operations, Masaya Maeda. Lot's of variations on "No Comment," but there was one interesting answer to a question about possible issues with the sensor 'heating up' when shooting extended movie clips (an issue I wasn't even aware of until the announcement of the Nikon D90, when that was given as the reason for the limit on movie clip length):


"We don't have that problem with heating because power consumption is very low in our newly developed sensors. There is no impact on stills image quality even after shooting extensively in movie mode."



UPDATE: I realize that it might be a bit confusing that I have a comment from a Canon guy and a reference to a Nikon Camera. The Canon guy is, of course, being asked about the movie mode in the Canon 5D Mark II. The Nikon D90 also has a movie mode, and when it was announced, there was talk that the clip length limit was due to heat build-up concerns (and I don't believe that has even been confirmed be Nikon.)


The 5D Mark II has an estimated clip length of 12 minutes, but reportedly that's an average based on the 4GB file length limit length, and is not due to concerns about heat buildup.


I hope this clears it all up!
