Sigma Lens For Canon Slr Camera

Sandy asks…A question for the DSLR guys?What are your thoughts on the Sigma SD1 Merrill Digital SLR Camera? The 40mp intrigues me, especially in a camera under 2 grand. I assume it's a proprietary lens mount too? I have a Canon 5D2 and a 60D that I use EF-L series lenses with. Would I be able to use those lenses on the Sigma or more likely, will I be able to buy an adaptor ring? If it's worth it I don't mind going into a whole new system, I have 3 Canon EOS DSLR cameras and 2 Pentax DSLR
