Ginko:
I was speaking about the developers who have already begun Xbox 2 development and those who have a general interest. The point being that there\'s obviously something worth noting about XNA whatever the intentions might be.
AFAIK, the only developers that have started development on Xenon are 1st parties. This most definately includes Rare. Since most 1st party developers of Microsoft have a PC background, their interest comes to no suprise as they have been working with similar framework and middleware for the last few years (DirectX). Don\'t want to put them down in any way, but AFAIK no big 3rd parties have really started actual development (perhaps planing stages?) yet. Therefore, I can\'t comment on how big interest is and why.
What I do know is, that the above scenario that I listed with CELL workstations could be a serious dent in XNA\'s plans and future. Not only that, but it seems Sony and IBM are working on to provide something similar as an API.
