The Royal Society of London will launch a new open access journal this fall, Royal Society Open Science (RSOS). RSOS will operate similarly to PLoS One, meaning it will publish research in all areas of science and mathematics and will base peer review on quality of the research, not novelty of the subject.
For more information about this journal, see this article from The Guardian: http://www.theguardian.com/science/grrlscientist/2014/feb/18/royal-society-open-access-science-maths-new-journal
