Yeah I have read that post before and made a post regarding any information about any new releases or new support for the mod tool with XNA (which can be found here: http://creators.xna.com/forums/thread/6462.aspx). Also I posted on the XSI forum which can be found at this link : http://forum.softimage.com/topic.asp?TOPIC_ID=8540
Also I think someone said the .x format doesn't support animation. Is this true?
As far as other importers I saw someone working on a Quake 3 library for handling Q3 content formats. That might be useful if I export to another package and then save the files out. Has anyone been working on a .smd importer maybe?
