How much of the market is exclusively Blu?

[Merlins]

Depends on how you are counting. Number of studios, number of exclusive titles, market size on theater, market size on DVD, stock share etc. and under which time frame.

However. it is about 70-85% for Blu-ray in most numbers except number of titles. Universal did push out a lot of catalouge titles last summer but the picture quality shrunk at the same speed.

Here is a couple of examples:

And remember that this is only the studio support. Add extra retail support, software support and a lot more CE-support and you will understand that HD-DVD is pretty much only Toshiba and Universal+Paramount that does not release so many movies these days...
