I'm not saying Nikon can't make a raw capable product. Just pointing out that they are very cautious in regards to the video market.
It's totally a different argument to be made when you're dealing with the immense effort of developing a product with the intention of penetrating a video market that's been dominated by the likes of Canon, Panasonic and Sony. Being a new entrant to any market, there's no guarantee of success with the competition... and the payback period can be uncertain.
While impressive, that random German guy isn't going to be able satisfy a large market demand.. look at Black Magic and their long wait times for their cameras as case in point. You can't forget scale required in the business.. which all requires capital.
