Using development kits sales as a base for such estimates doesn't make much sense. Development kits have low resolution, cause motion sickness, there are no playable games for them, you need to wait 1+ month for one. It is safe to assume that the kits were bought mostly by developers willing to experiment with the new platform. It is very hard to estimate how many end users will buy Oculus based on this number.
