Unfortunately they aren't MERS-CoV genomes.
Nonetheless, a whole lot of new feline, porcine, murine, SARS, 229E and HKU1, genomes have been directly released from the J. Craig Venter Institute.
These now appear on GenBank with non-sequential accession numbers around the KF272920-KF530271. The sequences were produced using next generation sequencing technology.
Looks like the virome is in the sights of the big data guys.
