BGI / CompleteGenomics just released the Revolocity sequencing platform.
And this news article and blog post
The selling points are that it offers and end to end solution, from sample to VCF file (gVCF?) and can sequence a comparable amount of samples as the x10. Nice if you are happy doing exactly what BGI offers, not so much if you want more flexibility.
What really surprised me though is that the read length is 28 bp paired end. That is 5 x less compared to 150bp on the x10. Surely this affects the mapping quality of the reads and the type and quality of variant calls you can make.
