Import or convert dotXSI

Hello, I’m going to be working on some models for a commercial game so I’ve just started using Blender. Been working with Maya for a while, but my liscense doesn’t cover commercial work. I’ve been using Blender for a couple days now and I’m really getting the hang of it. Its a good program for what I need.

The problem is I have to be able to import the game’s dotXSI files to work with them. So I need some kind of plugin or script for Blender to do this. Another option is if anyone knows a program (or 3D software) that can convert dotXSI into a file type that Blender can import.

Any ideas?
