Illumina announced in January at the JP Morgan Healthcare conference the NextSeq 500, which was trumpeted (at least at the level of press releases and public relations) of being available immediately. Knowing first-hand how difficult it is to launch a new system, I had expected the first systems to ship by the end of the first quarter (March), but here we are in mid-June and the first data is only now being reported on the NextSeq 500 system.
