Record time historically has been limited due to EU regulations taxing cameras differently based on whether they record less than 30 minutes or more. However, sensor heating is another issue certainly.
These DSLRs as far as video has been concerned have been pushed by those in the film market. Where takes are generally several seconds to something no longer than 3-4 minutes. In that context, the 30 minute limit is a non-issue. As was the previous 12 minute limit of the Canon DSLRs and the 8 minute limit of the Nikons.
