Complete genomics has some publicly available datasets. I am sure there is a converter to VCF. If you have an FTP server, webspace or somehow to share data, I would be happy to send you the 200 Danish exomes in VCF.
VCF is a very flexible format & I would be careful converting Complete Genomics directly into VCF on your own -- for example Complete handles complex variants very differently compared to how 1000G handled them in the Pilot phase. Digging into the supplemental information on the Korean genome publication etc. can help fill some of those extra fields.
Also, the genomes you've mentioned contain Structural Variation data of various degrees of completeness -- and VCF files do exist for these kinds of variants as well.
By VCF file, do you mean you're interested in the format itself, or a particular kind of variant?
