I don't really think the project will end any time soon, because isn't DNETC doing a similar type of project? They're not even close to being done, and they're using HUGE amounts of GPUs...
...this project on CPU alone would take forever. When they port it to GPU, we might see it finish much sooner, depending on the credit they give out, and if we're all willing to throw thousands of high end GPUs at it.
But...by then we'll have SO MANY MM credits on this puppy that we'll actually be happy when we do crack it and the project completes successfully.
