While CRISPR is an incredible technology with plenty of current exposure, the Nobel Prize in Medicine tends to move slowly; often discoveries that first debuted 20 years ago are only finally recognized. CRISPR will have its day in the Nobel sun, but unlikely in this decade.
Very true. It took 8 years for Craig Mello and Andrew Fire to be awarded for RNAi (published 1998, awarded 2006 -- and that was considered fast). CRISPR as a gene engineering tool isn't even that old yet, so we've got a few years.
Don't give up hope, yet. CRISPR could be awarded for the Nobel Prize in Chemistry. The Ribozyme discovery was a Chemistry Nobel [1]. And, yes, Nobels take decades to come to fruition.
