I know where you are coming from bit I think it a bit off target, and falls
into a common repeat line of reasoning.  Direct3D is used under Windows and
XBox by games developers.  The games market is far bigger than just Windows
and XBox.  The Windows + XBox while being a big player, it is far from the
biggest market in the games industry, but sometimes from online traffic it
would seem that it's the only game in town, this is just PR or ignorance
though.   The biggest recent games platforms have been PlayStation 2 and the
more recently the Wii, neither of which have D3D or OpenGL.  I believe Wii
has a OpenGL style graphis API.

For the next generation of games I think we have shout.  I think to
successfully push the OSG to the games market one has to emphasis the
portability and the wider market reach that it brings.  Getting the message
over about a wider market reach is easy to those who've already climbed out
of the Windows centric box, but for those who just think Windows == 100%
games market it's a harder sell.  It's this perception that needs to be
cracked first.

Self selective survey's can be of use for particular interest groups, but
rarely mean much outside the selective group.  The above survey basically is
100% of who answer a suvery for a D3D centric game/company had support for
some version of D3D...

Interesting link.  I hadn't come across this before.
