Found this one at C&D...Can't really tell much from it though. Looks like larger wheels in the back. I think the "front vent window" is part of the camoflauge. Distinctive Eclipse grill in the front.

I remember seeing that a long time ago and the date on that page explains it.
The concept shown at NAIAS from Mitsubishi is a preview of the newest Eclipse. I can't remember what the concept was called but it was orangish/black color and looked like the current gen Eclipse with huge rims. I'll try to find it and post up the pics for you.

PS I don't think a Turbo will be offered but they may add it later in the coming model years.
