The front page of the Notices (Jan 2011) is an advertisement for the "Bulletin of Mathematical Sciences". The "Aims and Scope" are:
The Bulletin of Mathematical Sciences, a peer-reviewed free access journal, will publish original research work of highest quality and of broad interest in all branches of mathematical sciences. The Bulletin will publish well-written expository articles (40-50 pages) of exceptional value giving the latest state of the art on a specific topic, and short articles (about 10 pages) containing significant results of wider interest. Most of the expository articles will be invited.
One of the executive editors is Efim Zelmanov, so that certainly counts as a "big-shot" getting behind the effort.
