"One thing we know for certain, 3M have paid for previous evaluations, cant see why they wouldnt be paying this time around, in fact I'd be almost certain they are."

We don't know this for certain. Please direct me to where OBJ have announced that 3M have paid for previous evaluations. Nor has it been said that those $800K revenues where made from product evaluations. They have received revenues from a research collaboration agreement with a FMGC company of which they where to receive US$355K (announcement made prior to 2009 financial year). In fact OBJ where quick to point out that revenues where being made from such an agreement.
If other revenues where being made from similar agreements OBJ would be quick to point those out also.
